针对某发动机配气阀座和阀体上平衡活塞用材的实际需要，利用中频感应加热的热压法研制出以超级镍合金为基体，以银和石墨为润滑相和以ＳｉＣ硬质微粒为弥散相的不同配方的几种高温自润滑复合材料，并就其物理机械性能和摩擦磨损性能进行了系统的试验研究与对比，从中筛选出一种制作成配气阀座和平衡活塞，在某发动机的规范工况下正常运行了１２００秒，各项技术指标均已达到规定的要求．
In view of the actual need of balance valve material on valve seat and valve body, the super nickel alloy was developed by hot pressing with medium frequency induction heating. Silver and graphite as lubricant phase and SiC hard particle as dispersion Phase of different formulations of several high-temperature self-lubricating composite materials, and its physical and mechanical properties and friction and wear performance of a systematic experimental study and comparison, from which to choose a made into a valve seat and the balance of the piston, in an engine Normal operation under normal operating conditions for 1200 seconds, the technical indicators have reached the required requirements.
