用三种能量的 N~+离子重叠注入和用N~+离子反冲注入两种方式研究了注入对轴承钢—铍青铜磨损性能的影响。磨损试验是用未注入的Q Be Z 铍青铜针在注入的 G Crlo 轴承钢样片上滑动。反冲注入的钢片上镀有 Cr 膜,这种注入方式使摩擦付双方的耐磨性能都得到了明显改善。重叠注入对铍青铜的耐磨性改善明显,而轴承钢是否改善有待探论。注入减少了粘着磨损。在注入层内观察到的氮化物、Cr_2O_3及表面 C 污染形成的石墨态对改性都可能有利。
The influence of the injection on the wear properties of bearing steel - beryllium bronze was studied by three kinds of energy N + ions overlapping injection and N + ion recoil injection. Abrasion tests were performed on uninjected Q Be Z beryllium bronze pins on injected G Crlo bearing steel coupons. The recoil implanted steel is coated with Cr film, this injection way to make friction wear both the wear resistance has been significantly improved. Overlapping injection of beryllium bronze wear improved significantly, and the bearing steel is to be explored. Injection reduces adhesive wear. In the injection layer observed in the nitride, Cr 2 O 3 and surface C pollution of the graphite state of the modification may be beneficial.
