摘    要:
论述了QPQ盐浴复合处理技术的发展和基本原理。工件经过QPQ技术处理,表面形成一层致密的氧化膜。试验模拟工件在高速低载荷的工作环境下,对QPQ渗层的表面摩擦磨损特性进行分析,通过改变速度、载荷等外部因素,测试摩擦系数的变化。试验结果表明,与未经过QPQ处理的工件相比,其摩擦系数、磨损率均极低,性能极大地满足了材料在低载高速的工作环境下的使用要求,并有一定的稳定性。

关 键 词:盐浴复合处理  氧化膜  磨损率  稳定性

Abstract:
This article provides an overview of development and the basic principles of the QPQ complex salt bath heat treatment technology. After the QPQ technology processing, a layer of dense oxidation film will be formed on the surface. High-speed and low-load bead work environment were simulated in the test, and workpiece's friction and wear characteristics were analysed. The results show that,comparing to other types ,QPQ carburized layers have low friction coefficient ,low wear rate. Such capabilities are useful to work in the high-speed, low-load work environment requirements,and it have a certain degree of stability.
Keywords:compound treatment   oxidation film   wear rate   stability
