激光表面织构化PTFE在边界润滑条件下防爬行现象作用研究
Laser Surface Textured PTFE Inhibitation for Stick?Slip Phenomenon Under Boundary Lubrication
摘要
Abstract
When the machine tool is in the start-and stop-stages,the stick-slip phenomenon will be observed and high-precision positioning,machining accuracy and fretting feed will not be guaranteed. The most critical reason is that there is the difference between the dynamic and the static friction coefficients. Textures with different area ratios are fabricated on the surfaces of the upper PTFE-based composite and the friction tests are carried out on a reciprocating tribotester under the boundary lubrication and flat-on-flat contact conditions. The results show that there exists an optimal textured area ratio of 19.6％ that can minimize the difference between the dynamic and the static friction coefficients.关键词
