摘要
为了延长航空发动机主轴轴承的使用寿命,在自制的双元素离子注入机上对GCr15和M50两种轴承钢材料的试样、轴承试验件和正式轴承零件进行了双元素离子注入,注入能量为100keV。经检测,GCr15和M50两种材料经N、Ti两种元素注入后,摩擦系数和耐磨损、耐腐蚀、抗疲劳等性能都得到了显著提高。轴承的内外套圈、滚柱和钢球注入的均匀性都达到了87%以上。
In order to extend service life of the main shaft bearing of turbine engines, GCrl5 and M50 steel samples and bearings were implanted with 100 keV N and Ti ions. Properties of the implanted samples were determined. The results show that the friction coefficient, wear resistance, corrosion resistance and fatigue resistance are enormously improved by the N + Ti ions implantation. Implantation uniformity of the bails, rollers and rings of the bearing is over 87%. The implanted bearing has stood the proof by the production enterprise.
