摘要
在用纯水作工作介质的液压传动中 ,液压元件的耐磨性和抗蚀性是水压传动中材料选择所面临的两个技术性难题。QPQ盐浴复合处理技术是一种新的金属盐浴表面改性强化技术 ,能大幅度提高金属表面的耐磨性和抗蚀性 ,且处理后的工件变形很小。本文简要介绍了QPQ处理技术的工艺方法及经QPQ处理后的材料用于水压元件的应用试验 ,证明了QPQ处理技术用于水压元件的可行性 。
The characteristics of anti-wear and anti-corrosion of hydraulic components are two technical problems of choosing material in the field of hydraulics. The QPQ salt bath composite treatment is a new modified technology to strengthen the metal surface. Not only can the characteristics of anti-wear and anti-corrosion be increased greatly, but also the workpiece less deformed after QPQ treatment. The technological method of QPQ treatment technology and the test of materials with QPQ treatment in water hydraulic components were introduced in this paper. The feasibility that QPQ treatment technology can be applied to water hydraulic components was testified. A new way to choose material of water hydraulic components was provided.
