固体材料及其改性后表面耐磨性的测量与评估

Measurement and Evaluation for Wearability of Solid Materials Their lmprovement

介绍了对固体材料及其改性后表面（厚度约１μｍ左右）耐磨性的测量与评估。提出在定义材料耐磨性时应考虑其密度，即在特定的压力和研磨对偶材料相同以及保证磨损面积及研磨时间一致的条件下，材料耐磨性的大小应由被磨损的体积来确定。对不锈钢片溅射Ｓｉ＿３Ｎ＿４，Ｎｂ＿２Ｏ＿５膜及不锈铜片本身的耐磨性做了比较。

The wearability of solid materials before and after improvement is discussed.Density showdbe taken into consideration. The wearabilities of sputtered film of Si_3N_4 and Nb_2O_5 and of stainlesssteel substances are compared
