采用离子注入技术提高航空发动机油泵柱塞寿命和可靠性研究

The Studies of Ion Implantation for the Improvement of Service-Life and Reliability of Aero-Engine Fuel-Pump Plunger

介绍了选用 N,Ti,Cr,Ag 等元素,采用直接注入和离子束混合两种工艺方法对燃油泵柱塞(Cr12MoV)、斜盘(Cr4Mo4V)进行离子注入所引起的性能变化以及实际零件经过上述方法处理后的200h(1:3)等效台架试车情况。

The variation of surface properties of Cr12MoV fuel-pump plunger and Cr4Mo4V inclined disk implanted hy N, Ti, Cr, Ag respectively by the ion implantation and ion beam mixing processes is reviewed.
