摘要: 利用MMU-5G型端面摩擦磨损试验机,研究不同磨损时间对45钢-45钢摩擦副磨损表面自修复膜生成的影响及其机理,借助KYKY-2800型扫描电子显微镜测试分析摩擦副的表面和自修复层形貌及表面成分组成。结果表明,磨损时间对添加剂在磨损表面形成自修复膜影响显著;摩擦磨损时间为24h时,试样失重为零,试样磨损表面自修复膜生成;自修复膜的生成使得试样摩擦磨损表面平整光滑,可以有效降低金属磨损。

Abstract: The influence of different wear time upon the formation of self-repair coating on the worn surfaces of 45 steel pairs and mechanism thereof are investigated by using MMU-5G end-face friction and wear tester. By using scanning electron microscope(SEM) and Energy dispersive X-ray(EDX), The surface of rubbing pairs and appearance of the self-repair coatings and their chemical composition are tested. The experimental results indicate that the wear time has a great influence on the formation of self-repair coating on the worn surface. When the time of friction and wear is 24 h, the sample weightlessness is zero, the self-repair coatings of the sample’s worn surface are formed, which makes the surface smooth and the metal wear reduced effectively.

Key words: Additive, Friction and wear, Self-repair
