Resistance Improvement

One of the directions of wear resistance improvement is microalloying of improved steels. In the studies conducted, the feasibility of adjusting the composition of steel 30Н3MF was determined by additional microalloying of V + Nb in order to give it wear-resistant properties. Microstructural studies of the experimental alloy were carried out. The microstructure is fairly uniform, represented by a matrix and inclusions. Matrix is represented by doped solution, which includes nickel. It is determined that in a chemically and structurally inhomogeneous ingot, even after heat treatment, structural components will remain. Characteristics such as the amount, morphology and distribution of non-metallic inclusions in the metal matrix are mainly laid at the stage of metal discharge from the steelmaking unit, as well as in the process of deoxidation and modification of steel during its off-furnace treatment.

Influence of different type heat treatment including high temperature quenching on wear resistance has been investigated. The two investigated steels are widely used in production of mud pumps. It was shown that Kh12MFL had better wear resistance in comparison with 150KhNML. Martensitic-carbide structure of the steels formed by quenching from high temperatures (900 – 1000 °С) induced good hardness (61 – 64 HRC). Analysis of the residual austenite contents influence on wear resistance was also made. It was determined that residual austenite formed after high temperature quenching (900 – 1000 °С) was metastable and had tendency to transform into carbon containing martensite of deformation. This allowed steels to have maximum wear resistance because of providing high abilities to friction hardening of the work place of the sample.

Aisi 52100

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 paper presents the research results on produsing by the method of liquid-phase self-propagating high-temperature synthesis (SHS) the composite metal-matrix alloys intended for the obtaining of wear-resistant coatings by electric spark deposition (ESD). Oxides NiO, Cr2O3 and mineral concentrate ZrO2 were used as a melting charge. Alloys based on the Ni-Al system with aluminides of complex composition containing Cr and Zr were obtained by means of the alumothermic SHS reaction. Wear-resistant coatings were formed on steel 45 by the ESD method by means of the newly obtained alloys,. The maximum wear resistance of the coatings was obtained using the alloys containing Cr (wt% 18) and Zr (wt% 1.9).

There is investigated the wear resistance of mottled irons with stabilized carbide phase, obtained by alloying iron with copper, chromium and sulfur. It is shown that during heat treatment the outer shell of the carbide phase inclusions, destabilized with copper, dissolves, leaving a core stabilized with chromium. Carbon from the carbide phase dissolution coats the surface of manganese sulphide inclusions, forming additional wear-resistant structural component of mottled iron. The resulting structures can be attributed to compositional structures, which morphology and phase composition can be controlled by alloying and heat treatment.

The development of wear-resistant materials with excellent properties is of great research value in the manufacturing industry. In this paper, a new kind of low-vanadium wear-resistant alloy was designed and characterized to unveil the influence of vanadium content coupling with heat treatment on the microstructure, hardness, and abrasive wear property. The performances of commercial high chromium cast iron (HCCI) and the new low-vanadium wear-resistant alloy are compared. The alloy with 3 wt.% vanadium quenched at 900 °C and tempered at 250 °C, possessing VC, Mo2C, and M7C3 distributed in the martensite matrix, displayed a wear resistance two times better than the HCCI. The results showed that the increase of vanadium content from 0.98 wt.% to 3.00 wt.% resulted in a decrease in the size of M7C3 and a more homogeneous distribution of M7C3. VC with a bimodal distribution is effective for impeding grooving or indenting by abrasives because of their high hardness, which plays a vital role in improving the wear resistance of low-vanadium wear-resistant alloy.

Aluminum metal matrix composites were used in various fields such as aircraft, underwater, automobile, aerospace. Several fabrication techniques were used for the production of these composites. Among the various methods, the powder metallurgy route provides dimensional accuracy and high production rates. In this paper, metal matrix composites that include 7075 aluminum alloy chips and Al2O3 particles were produced by using a hot pressing. The effect of reinforcement amount and T6 heat treatment on the mechanical and wear properties of the composites were investigated. Al2O3 particles were added by weight of 5, 10 and 15 % and the composites were produced by hot pressing. T6 heat treatment consisted of a solution treatment at 480?C for 2 h and artificially aging process at 120?C for 24 h. Wear resistance of the composites was determined by a ball-on-disc dry sliding wear test. Brinell Hardness of the composites tended to increase with the increasing Al2O3 reinforcement up to 10 wt.% and with T6 treating. Particle reinforcement improved the wear resistance up to 10 wt.% Al2O3. In addition, volumetric material loss tended to decrease after the aging process.
