Status and prospects of surface texturing: design, manufacturing and applications

Abstract

In recent years, the requirements for high-quality development in the manufacturing industry and extreme application conditions have increasingly demanded higher equipment performance. The surface and interface condition of components is directly related to the stability, reliability and service life of equipment. The development of high-performance or multi-performance surface texturing is of great significance for the effective improvement of mechanical properties, optical properties, catalytic properties and biological properties of surfaces. This paper summarizes the application of textured surfaces in improving the physical, chemical and biological properties of surfaces; outlines the types of texturing patterns and the design methods; analyzes the main technical methods and their characteristics for the preparation of surface textures in additive manufacturing, subtractive manufacturing and equal material manufacturing; and makes outlooks on texturing surfaces from the aspects of performance enhancement, pattern design and manufacturing technology in combination with the development trend of textured surfaces’ intelligence and digitization.

Study on Dynamics of Overrunning Spring Clutches and Suppression Methods for Their Abnormal Noise

“…Since dα is very small, we can approximate it as follows: sin dα 2 = dα 2 , cos dα 2 = 1, dF sin dα 2 = 0. Substituting Equations ( 10) and (8) into Equation ( 9), we obtain Equation (11):…”

“…However, there is a noticeable absence of research describing optimization methods for addressing the dynamic abnormal noise issues in overrunning spring clutches. In the field of manufacturing and related domains, surface micro-texturing methods [9][10][11] are commonly applied for friction optimization. Liu et al [12] used laser technology to create three different shapes of laser micro-textures on the surface of hotrolled steel rail rollers to study the friction performance of wheel-rail steel.…”

Study on the Wettability and Abrasion Resistance of Ultrafast-Laser-Textured Ti Surface

“…In contrast, surface texturing techniques offer a means to enhance wear and corrosion resistance by controlling the material's surface morphology. The laser surface texturing technique is frequently employed to create a regular and uniform micrometer-scale morphology on Ti surfaces, which enhances the material's wear resistance [18,19] and represents a promising surface modification approach. Unlike traditional methods, ultrafast lasers act on materials for very brief periods with minimal thermal conduction effects, thereby avoiding thermal damage to the surrounding material.…”
