In this investigation, the sliding wear of polyetheretherketone (PEEK) against smooth (polished) and slightly roughened mild-steel counterfaces was studied under dry, lightly-loaded conditions. In this counterface roughness regime, the wear rate of PEEK decreased to a relative minimum as roughness increased. The worn system of PEEK against polished steel was simulated using several contact models. The application of a numerical non-Hertzian elastic stress analysis yielded estimates of subsurface stresses, which were correlated with results of wear particle morphological studies. As counterface roughness increased, minor changes were observed in the wear mechanism. Wear particle morphology, however, displayed evidence of mechanical counterface interaction resulting in interfacial film formation and reduced wear.

Corrosion Behaviors

Dry sliding wear and immersion corrosion behaviors of Al 5083-based hybrid composite reinforced with multiwalled carbon nanotube (MWCNT), Molybdenum boride (MoB) and nickel (Ni) are studied with different weight percentages. The reinforcement weight percentages of MWCNT ranges from 0 to 1.5, that of MoB from 1 to 4 and for Ni from 2 to 8. Dry sliding wear behavior at room temperature is studied using Pin on Disc by varying the sliding distances from 500 to 2000m, load from 10 to 40 N and sliding velocity from 0.25 to 1.75m/s. The wear studies revealed that there is a considerable decrease in wear rate for composites than the alloy material with increase in %wt of reinforcements for all test parameters. The worn surface analysis revealed that there are two types of wear mechanisms namely abrasive and adhesive. The uniform immersion corrosion tests also showed decreasing rate with increase in reinforcements.

The nano crystalline thin coating of NiFe and NiP C has been successfully carried out by using electroplating technique in order to enhance the structural and mechanical properties of mild steel. The NiFe & NiP thin layers were coated on mild steel at constant current density and pH over a deposition period of 30 minutes. All the coated mild steel samples were subjected to various characterization techniques like X-ray Diffraction method (XRD), Vickers hardness, surface roughness and wear test to reveal the effect of NiFe and NiP on mild steel. The mechanical properties such as surface roughness and wear behavior were investigated by using Stylus profilometer and Pin on disc method. The coated mild steel exhibits enhanced mechanical properties than that of uncoated mild steel. The variations in structural and mechanical properties of coated mild steel were also studied.

Chromium (Cr), Copper (Cu), Cobalt (Co), Ferrous (Fe) and Nickel (Ni), the HighEntropy Alloys were mixed to form analloy. A die was created using OHNS (OilHardenedNickelSteel).Thealloyed powderwasloadedintothedieandaloadof13KNwas applied. Universal Testing Machine (UTM) was used for the load application. Afterpressing, the specimen was kept inside the Muffle Furnace for heating at 600°C for sintering. After heating, the surface of the specimen was smoothened byroughing. The weight of the specimen was noted, before and after the wear test.The specimen was subjected to wear test in Pin on Disc Machine. Wear rate of thespecimen was calculated. This specimen was used to coat the Single Point Cuttingtool. This coating of tool was done to decrease the wear rate and increase the lifeofthe tool.

 The aim of the present research is to study the effect of cadmium addition on microstructure and wear behavior of the alloy (Al-12%Si) under dry sliding conditions. Wear behavior was studied by using the Pin-On- Disc technique under different conditions at applied loads 5-20 N, at constant sliding speed and in constant time. The steel disc hardness was 35HRc. All alloys were prepared with different percentages of cadmium (1.0, 2.0, 3.0) wt%. Also the base alloy was prepared by melting and pouring the molten metal in a metallic mold. It was found that the cadmium addition to Al-Si matrix decreases the wear rate and improves the wear properties for alloys containing -Cd under loads above 10N. It was also found that the alloy Al-12%Si containing 3%Cd is the best alloy in wear resistance and friction coefficient. This is due to presence of the Cd-phase as cuboids or hard particles distributed in a eutectic matrix which reduces the friction coefficient at high loads (20N).

In present paper, the dry sliding wear behaviors of wrought Al-12.7Si-0.7Mg alloy have been investigated using a pin-on-disc machine. The effect of various parameters, such as alloy conditions, sliding speed, and normal pressure, has been investigated. Wear surface was characterized by SEM/EDX microanalysis. The microstructure, hardness and tensile properties of the extruded profile were investigated with the aim of understanding the wear and friction mechanisms. The present results reveal an improvement in the mechanical and tribological properties, obtained due to microstructure characterized by fine Si particles uniformly distributed in the Al matrix of fine equiaxed grains, as promoted by hot extrusion. It was also revealed that higher hardness and the lower aspect ratio of eutectic Si particles contributed to the better wear resistance.

This article statistically investigates the effect of various parameters such as material factors: silicon carbide (SiC) reinforcement, graphite (Gr) reinforcement and mechanical factors: normal load, sliding distance and speed on the sliding wear rate of vacuum stir cast self-lubricating AZ91D-SiC-Gr hybrid magnesium composites. The sliding wear tests have been performed on pin-on-disc tribometer at 10-50N loads, 1-3m/s sliding speed and 1000-2000m sliding distance. It has been examined that hybrid composites yielded improved wear resistance with reinforcement of SiC and solid lubricant graphite. ANOVA and signal-to-noise ratio investigation indicated that applied load was the most critical factor influencing the wear rate, followed by sliding distance. Further, the AZ91D/5SiC/5Gr hybrid composite has exhibited the best wear properties. From the SEM and EDS analysis of worn surfaces, delamination was confirmed as the dominant wear mechanism for AZ91D-SiC-Gr hybrid composites.

In water cooled reactors, the friction between spacer grid and fuel rod can lead to severe wear and it is an important topic to study. In the present study, sliding wear behavior of zirconium alloy was investigated in water and dry state using the pin-on-disc sliding wear tester. Sliding wear resistance of zirconium alloy against heat treated inconel alloy was examined at room temperature. The parameters in this study were sliding velocity, axial load and sliding distance. The wear characteristics of zirconium alloy was evaluated by friction coefficient, specific wear rate and wear volume. The micro-mechanisms responsible for wear in zirconium alloy were identified to be micro-cutting, micro-pitting, delamination and micro-cracking of deformed surface zone.
