Research progress of surface texturing to improve the tribological properties: A review

Abstract

In the process of machine and mechanical operation, it is inevitable to face problems such as friction and wear. At present, there are many solutions to solve the problems. As a very effective method, surface texturing has been applied in many projects. In recent years, surface texturing has made great achievements in the study of friction pair surface, which is of great significance to improve the tribological properties of friction pair surface. In this paper, the author reviews the main research results of surface texturing in controlling friction in recent years and points out the research purpose and development status of surface texture. The preparation of texturing is summarized and analyzed from two aspects: shape and size control accuracy and surface quality. The research on the anti-friction mechanism of texture is reviewed, and the three states of dry friction, fluid lubrication, and boundary lubrication are analyzed, respectively. The optimization of morphology and parameters was discussed, and the optimal parameter range was obtained. Finally, the above aspects of the full text are summarized, and the problems faced by all aspects are put forward. Combined with the actual situation of the current research, the future development prospect of surface texture technology is prospected.

“…In this three-point stencil, n is the current iteration number, so P ( n+1) represents the unknown pressure and coefficient b i,j may be a function of P ( n) that is the known pressure from the initial guess or the last iteration. The coefficients, α i,j , β i,j , γ i,j , b i,j , ought to be provided by discretizing all the terms in equation (1).…”

“…Surface texturing, as a means of material surface treatment, has been proven to effectively improve surface friction performance [1,2]. It has been widely applied in many engineering projects, such as bearings, tools, and gears [3][4][5][6].…”
