1.
The variation of surface roughness and surface topography of the experiment wheel were measured step by step and the wear mechanism was revealed as that adhesive wear dominated,followed by oxidation wear and fatigue wear,and abrasive wear was obsevered only occasionally.
通过分阶段观测渗镍高速工具钢实验轮表面粗糙度和表面形貌,揭示出粘着磨损机理占主导,疲劳磨损和氧化磨损机理其次,磨粒磨损机理比重最小;其次通过分阶段测定实验轮质量、几何尺寸等参数变化规律,计算出其磨损率比渗镍前至少下降约57%。
