本文阐述用电子扫描显微镜对光球板板沟表面试样进行观察和分析的结果,证实了光球板的磨削机理是:1.沟道表面呈颗粒状,凹凸不平,相当于硬质磨料;2.起主要磨料作用的是马氏体而不是碳化物;3.钢球表面的金属脱落是属于磨料磨损;4.板沟表面的金属脱落有表面疲劳磨损和磨料磨损两种形式,而主要是属于表面疲劳磨损。 This paper describes the use of scanning electron microscopy of the optical ball plate groove surface samples were observed and analyzed the results show that the optical ball grinding mechanism is: 1. The channel surface is granular, rugged, equivalent to hard abrasive ; 2. The role of the main abrasive is martensite rather than carbide; 3. The ball off the surface of the metal ball belongs to the abrasive wear; 4. Plate groove surface metal surface wear and abrasive wear off two forms, and Mainly belong to the surface fatigue wear.
