Abstract

The mechanical friction leads to a large amount of energy consumption every year. To decrease the friction and wear and prolong the service life of the working components are therefore significant for energy sustainable development. To this end, many researchers investigate how to improve the tribological and wear resistance of the components by mechanical machining. The current article reviews the influence of common mechanical processes (i.e., grinding, turning, and milling) on the wear performance of machined surfaces in terms of hardness, surface morphology, and residual stresses. The strengthening mechanism of machined surface in the wear performance can be attributed to (i) the high hardness that improves the wear performance by preventing the insertion of wear particles on the friction surface; (ii) the induced surface texture that improves the wear resistance by storing the lubricating oil and wear debris for alleviating the subsequent friction; and (iii) the high compressive residual stress that mitigates the surface worn by preventing the formation and propagation of crack defects. In order to service under different conditions, it indicates that the control of hardness, texture, and residual stress by optimizing the process parameter could improve the wear performance of the machined surface. This review can deepen the understanding of the enhancement mechanism of wear resistance of the mechanically machined surfaces to obtain the better performance of components.
