温度对6061铝合金摩擦磨损行为的影响
Influence of Temperature on Friction and Wear Behavior of 6061 Aluminum Alloy
摘 要
采用球盘摩擦磨损试验机研究了温度(25,200,300,400,500 ℃)对6061铝合金摩擦磨损行为的影响, 通过分析铝合金磨损后的表面形貌和微区成分研究了其在不同温度下的磨损机制。结果表明: 随温度升高, 摩擦因数呈先增大后减小的趋势, 磨损率显著增加, 磨损机制从磨粒磨损逐渐变为氧化磨损、粘着磨损以及严重的塑性变形磨损。

Abstract
Influence of temperature(25,200,300,400,500 ℃) on friction and wear behavior of 6061 aluminum alloy was investigated by using ball-on-disc tester, and the wear mechainism at different temperatures was studied by analyzing the surface morphology and composition of the aluminum alloy after wear. The results show that, with the increase of temperature, friction coefficient increrased and then decreased, wear rate increased markedly, and wear mechanism changed gradually from abrasive wear to oxidation wear, adhesive wear and severe plastic deformation wear.
