Aisi 52100

Abstract AISI 52100 bearing steels are commonly used in applications requiring high hardness and abrasion resistance. The bearing steels are working under dynamic loads in service conditions and their toughness properties become important. In order to provide the desired mechanical properties, various heat treatments (austenizing, quenching and tempering) are usually applied. In this study, AISI 52100 bearing steel samples were austenized at 900°C for ½ h and water quenched to room temperature. Then tempering was carried out at 795°C, 400°C and 200°C for ½ h. In order to investigate the effect of heat treatment conditions on wear behavior, dry friction tests were performed according to ASTM G99-05 Standard with a ‘ball-on-disk’ type tribometer. The samples were tested against steel and ceramic counterparts using the parameters of 100 m distance and 30 N load and 0.063 m/s rotational speed. After wear test, the surface characterization was carried out using microscopy. Wear loss values were calculated using a novel optical method on both flat and counterpart specimens.

A new iron-based wear resistance alloy was developed to replace the Co-containing Stellite 6 alloys in nuclear power industry. The effect of B addition on the wear resistance was investigated. Sliding wear tests of Fe-Cr-C-Si-xB (x = 0.0, 0.3, 0.6, 1.0 and 2.0 wt%) alloys were performed in air at the room temperature under a contact stress of 103 MPa. Low-boron alloys containing less than 0.6 wt% boron showed an excellent wear resistance than any other tested alloys. The improvement was associated with the matrix hardening by promotion of the γ→α′straininduced martensitic transformation occurring during the wear test. However, the alloys containing more than 1.0 wt% boron showed slightly increased wear loss compared to the low-boron alloys because of the absence of the strain-induced martensitic transformation and the presence of the brittle FeB particles, aiding crack initiation.

In order to choose the rubber material and improve the service life of Progressing Cavity Pump (PCP ) when exploiting offshore crude oil, it is important to analyze friction and wear behaviour of stator and rotor of PCP in the mixture of crude oil with different water content. The friction and wear test about Nitrile -Butadiene Rubber (NBR) and Fluorine Rubber (FKM) were carried on ring-on-block tester, the wear loss was observed by electron microscope, the wear mechanism was also discussed. The results show that: (1) FKM owns better wearing resistance than NBR in the mixture of crude oil with different water content; (2) when the content of water in the mixture is less than 26%, the frictional coefficient of sample is 0.05, due to the oil film between the friction pairs; (3) when the content of water in the mixture is more than 26%, the frictional coefficient increases to 0.4, because of the water film between the friction pairs.

Due to its high hardness and wear resistance under rolling contact, AISI E52100 steel (JIS SUJ2) is used in the manufacture of bearings and linear guides. The life estimation methods for components working under rolling contact developed up to now were designed for bearings. In this study, fatigue testing under reciprocating motion was performed and based on the microstructure, wear track investigation as well as hardness and retained austenite measurements, an evaluation method for linear guides is proposed. The results obtained from three different areas of the sample including wear tracks and non-damaged area are as follows: (1) there was little microstructure difference between the center and the end of the wear track; (2) a clear difference of the retained austenite content at the wear track and at the non-damaged area could be observed, however the percentage within different areas inside the track was similar.

In this study, two different AISI 52100 bearing and D2 tool steels were subjected to ultrasonic nanocrystalline surface modification (UNSM) technique at ambient and high temperature of 500 °C. The objective of this study is to characterize the microstructure and to investigate the effectiveness of UNSM technique on the friction and wear behavior of those steels. The friction and wear behavior of the specimens against AISI52100 bearing steel ball with a diameter of 10 mm was carried out using a micro-tribo tester under dry conditions. The hardness with respect to depth from the top surface was measured using a microhardness. The change in the microstructure of the specimens before and after UNSM treatment was characterized by scanning electron microscopy (SEM). The findings from this preliminary study are expected to be implemented to the bearings and tools to increase the efficiency and performance of the components.

Aisi 316 Stainless Steel

This project investigates on salt bath nitriding process in order to improve the wear behavior of the material. This process increases the hardness of the material. The specimens were nitrided at 580°c on three different timing hours such as 60 minutes, 90 minutes & 120 minutes. A pin on disc machine is used to conduct wear test, so that wear loss can be determined. The specimens are to be magnified by metallographic test like scanning electron microscope. The untreated specimen is used to compare with the nitrided specimen. The best specimen is chosen which determines the life of material & improves the better wear resistance. The hardness of untreated material and nitrided material are compared. The material AISI stainless steel has many unique properties but it lacks wear resistance and hardness because of which it has limited applications. By conducting heat treatment operation, the hardness of the material does not improve, but by conducting case hardening process the hardness of the outer case will be high compared to base metal. If the hardness and wear resistance of the material improves the material can be used in wide range of applications.

Abstract Static Load Capacity as defined by Palmgren is the load (stress) applied to a bearing that results in an indentation greater than 0.0001 times the diameter of the rolling element. The effect of hardness on the Static Load Capacity of AISI 52100 bearing steel heat treated to six different hardnesses was investigated. Indentation, depth, diameter, volume, and surface area were measured by the white light interferometer. A total of 468 hardness ball–plate combination tests were conducted. For a given plate (race) hardness, the Static Load Capacity was dependent on plate (race) hardness and independent of mating ball hardness from Rockwell C 56 to 66. For plate (race) hardness between Rockwell C 56 and 60, the Static Load Capacity was relatively constant. At Rockwell C hardness between 60 and 61, the Static Load Capacity increased and then rapidly decreased at a plate hardness of Rockwell C 66, below that value obtained at Rockwell C 56. Experimental results obtained for Static Load Capacity using the Palmgren criteria correlated with the finite element analysis for ball-on-plate indentation but not with Hertz theory. The Static Load Capacity based on Yhland for ball bearings was equal to a maximum Hertz stress of 3.71 GPa (538 ksi) at a ball-race conformity of 52%. This value is 12% lower than that specified in the ISO and ANSI/ABMA Bearing Standards. The manufacturers’ Static Load Rating can be reduced from 4% to 7% for ball bearings and from 8% to 25% for roller bearings.

This work investigates Al 6061 alloy with graphite particle impregnated metal matrix composites under dry sliding conditions. The conventional casting techniques were used for preparing the composite material. Experiments were conducted under dry sliding conditions for determining the wear behavior of Al 6061 alloy- Graphite composite material with varying wt % graphite content under different sliding speeds and at different loads. Sliding distance of 250m was commonly used for the wear test. A pin on disc machine was used for conducting the wear test. The test was conducted under atmospheric conditions. Wear rate decreases with increased sliding speed and increases with increasing load. Worn surfaces of the composites were examined through scanning electron microscope. The wear loss of the composite material with 5Wt % graphite was found to be minimum with respect to sliding speeds and loads.

A metal matrix composite was developed through a unique liquid pressing infiltration process to study the wear mechanism of a TiC reinforced AISI 1020 steel matrix. The microstructure, hardness, and wear behaviors of the TiC/AISI 1020 composite were compared with commercial AISI 52100 bearing steel. Microstructural analysis showed that there were no defects, such as pores or agglomeration of reinforcement particles, and about 60% of the volume of TiC was uniformly dispersed. In the case of the AISI 52100 alloy, the hardness was 62.42 HRC, which was similar to the 62.84 HRC value of the as-cast TiC/AISI 1020 composite. After the quenching heat treatment, the Rockwell hardness of the composite increased to 76.64 HRC, which was attributed to the martensitic transformation of the AISI 1020 matrix. As a result of the pin-on-disc wear test with high contact pressure, the wear width of AISI 52100 was 2937 μm, which was approximately 4.3 times wider than that of the heat-treated metal matrix composite (682 μm). The wear depths of AISI 52100 and the heat-treated composite were 2.6 μm and 0.5 μm, respectively, indicating that TiC/AISI 1020 exhibited excellent wear resistance compared with bearing steel. Improved wear resistance of the TiC/AISI 1020 composite originates from uniformly distributed TiC, with an increase in the hardness due to the heat treatment.

The Stability

The tailoring of cermet composition to improve tribological properties requires careful choice of the type of secondary carbide. To investigate this aspect, a number of sliding tests were carried out on baseline TiCN–20Ni cermet and TiCN–20wt%Ni–10 wt% XC cermets (X = W/Nb/Ta/Hf) at varying loads of 5N, 20N, and 50N against bearing steel. With these experiments, we attempted to answer some of the pertinent issues: (i) how does the type of secondary carbide (WC/NbC/TaC/HfC) influence friction and wear behavior, and is such influence dependent on load?; and (ii) how does the secondary carbide addition affect the stability and composition of the tribochemical layer under the selected sliding conditions? Our experimental results reveal that the added secondary carbides influence chemical interactions between different oxides and such interactions dominate the friction and wear behavior. A higher coefficient of friction (COF) range, varying from 0.75 to 0.64 was recorded at 5N; whereas the reduced COF of 0.46–0.52 was observed at 20N or 50N. The volumetric wear rate decreased with load and varied on the order of 10−6 to 10−7 mm3/Nm for the cermets investigated. The cermet containing HfC exhibited high friction and poor wear resistance. At low load (5N), the abrasion and adhesion of hard debris containing various oxides dominated the wear, and resulted in high friction and wear loss. In contrast, the more pronounced increase in friction-induced contact temperature (below 500 °C) and compaction of hard debris resulted in the formation of a distinct tribochemical layer at higher loads (20N and 50N). The formation of a dense tribolayer containing oxides of iron and/or titanium is responsible for the reduced friction and wear, irrespective of secondary carbides.
