The Influence of Surface Texture on Abrasive Wear

Abstract

Friction happens everywhere. Abrasives generated in tribological process will result in secondary wear. Abrasive wear is a kind of rather common but harmful wear, which is the main reason for the damage of fifty-percent mechanical components by friction. Surface texturing is an effective method to improve the tribological and lubricating performance of tribo-pairs. In this paper, with different-size diamond particles added into the lubricant and a surface of the tribo-pairs textured by different parameters (diameter and depth) with femtosecond laser, the relationship between the surface texture and the abrasive wear was researched, and the influence of the texture on the abrasive wear was analyzed. The friction experiments were carried out on UMT3. The microstructures were tested and analyzed by SEM, microscope and White Light Interferometer respectively. The experimental results showed that the size of the surface texture, compared with that of abrasives, is the main factor which determines the friction coefficient. As the size of the surface texture is much bigger than that of the abrasives, the texture can accommodate the abrasives efficiently, and thus the friction coefficient is reduced efficiently.

Study on the Cutting Performance of Micro Textured Tools on Cutting Ti-6Al-4V Titanium Alloy

“…Feng et al [21] indicated that the cutting force and cutting temperature could be significantly reduced when a textured tool was used. As a conclusion, the textures on the tool surface can effectively reduce the tool-chip contact surface, reduce cutting temperature and cutting force, store lubricant, improve the contact state, and decrease the adhesion phenomenon [22][23][24][25]. However, the effect of sinusoidal textures and rhombic micro textures of tools on the cutting performance of titanium alloy is still unclear, which is necessary to be studied to further improve the cutting efficiency and surface quality of titanium alloy.…”
