<正> GCr15钢制精密轴承三种典型产品,刚玉砂轮和石墨砂轮加工的B2007112(以下简称B2007112刚、B2007112石)及B3-707,在疲劳寿命、显微硬度、形貌质量等性能测试对比中,依次较优.赵传国及靳九成等曾发现性能较优
The compositions and structures of the oxide films on three typical precise bearings have been investigated by means of Auger electron spectroscopic depth profile analysis as well as deconvolution and peak decomposition investigation of X-ray photoelectron spectroscopic depth profile. The results show that the bearing with best mechanical properties possesses the thinnest oxide film which is rich in C and poor in P, S impurities.
