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.

Meanwhile, features of increasing wear resistance due to the load redistribution from the polymer to the harder inclusions were discussed by many authors [44,45]. Loading with the fibers improved mechanical properties but was rarely discussed as a way to increase wear resistance.

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 …

The previously reported literature [74, [90], [91], [92]] showed that achieving excellent wear resistance necessitates a high-volume fraction of M 7 C 3 carbides within the austenitic …

An increase in the DCT time to 22 h did not lead to an increase in the wear resistance of 38CrNi3MoV steel, presumably due to an increase in hardness and brittleness in the absence of RA. Samples of 38CrNi3MoV steel with high hardness, hardened by conventional technology, also had reduced wear resistance.

An increase in wear resistance takes place only if a sufficient depth of hardening to resist cracking [Citation 57]. The ratio of surface hardness (H s) of the wear material to the hardness of the abrasive (H a) is a rate …

Therefore, in order to improve wear resistance, it was important to increase surface hardness to prevent plastic deformation of the surface layer. After nitriding, the sample surface generated a nitrided layer with a high hardness due to the γ N formation, which reduced wear to a certain extent.

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

A detailed review of wear resistance properties of austempered ductile iron (ADI) was undertaken to examine the potential applications of this material for wear parts, as an alternative to steels, alloyed and white irons, bronzes, and other competitive materials. Two modes of wear were studied: adhesive (frictional) dry sliding and abrasive …

In the production of critical parts for various machines and mechanisms, expensive structural steels are used alloyed with chromium, nickel, molybdenum, and vanadium. In practice, the wear resistance of parts, especially under severe operating conditions, may be insufficient due to uneven microstructure and the content of retained …

The results of this section indicate that increasing the molecular weight aid to improve the wear resistance of crosslinked UHMWPE. However, the reduction in wear loss reaches saturation when MW is about 3 million, which means that the wear resistance is limited to a certain level (0.33 mm 3). Other method needs to be explored for further ...

H13 steel improves wear resistance by a factor of 12 when the treated cylindrical sample is rubbed against a silicon carbide disk-counterbody [26]. PEB of medium carbon steel in a dry friction setting makes it possible to increase the wear resistance by a factor of 7.2 while decreasing the friction coefficient from 0.26 to 0.16 [27].

The wear resistance of alloyed manganese steel is affected by the martensitic phase transformation.
