The wear resistance of a steel shaft is to be improved by hardening its surface. This is to be accomplished by increasing the nitrogen content within an outer surface layer as a result of nitrogen diffusion into the steel. The nitrogen is to be supplied from an external nitrogen-rich gas at an elevated and constant temperature.

With increasing discharge current, on the other hand, the heat generated increases; hence, the role of UFG and nanograins in enhancing electrical wear resistance of copper electrode reduces. Also, this results in facilitating the action of vaporizing and melting and advances the impulse force in the discharge gap [ 30 ], thereby yielding a ...

In the abrasive wear test, with the increase of Ti content, the wear mechanism transforms from microplowing to microcutting. The matrix with more martensite and TiC particles effectively prevents abrasive grains from damaging the surface, and the wear resistance of the alloys is thus improved.

The wear resistance of titanium has been related to the sub surface deformation behavior [5], [64], [65]. From the experimental findings of Chan et al. [65] it has been demonstrated that wear resistance of Ti-based alloys increases with increasing

In comparison to AS-CN, TECN-x led to a lower COF owing to destruction of interlayer H-bonds. On the contrary, h-CN improved the wear resistance significantly by increasing interlayer H-bonds and forming a denser stacking structure. An extremely low specific wear rate (4.0 × 10 − 7 mm 3 /Nm) was achieved by simply filling 10 vol% h-CN …

In the model, the material loss is inversely proportional to the hardness, which is consistent with experimental observations for many materials. Based on the wear model, the cold-worked metal should possess enhanced wear resistance due to the increase in hardness caused by the strain-hardening mechanism.

There is a general tendency for wear resistance to increase as the hardness of the worn-out surface increases. However, a correlation between wear resistance and bulk hardness could not be detected. It can be inferred that the wear resistance is related to the bulk hardness and the scratch hardness on the worn-out surface, which depends …

Other factors that can have a negative effect on the wear resistance of the tool with an increase in temperature are a decrease in hardness and more intense cracking in the coating structure. As a result, due to the integral effect of the above-mentioned factors, the general tool wear resistance reduces with an increase in cutting speed.
