离子束动态混合技术在航空燃油泵上的应用研究

A Research of the Process of Dynamic Ion-beam Mixing Implantation Applied in the Pumps of Areo-engines

本文运用较为先进的离子束混合(IBM)注入技术,着眼于提高航空燃油泵耐磨性能和抗接触疲劳性能,进行了一系列试验研究。尽管离子注入的强化机理尚不十分清楚,一些理论和技术问题尚不成熟,但本文对于离子注入在航空精密偶件上的应用、高碳高合金钢表面改性等方面所作的偿试是有益的,其研究结果是比较令人满意的。

This article deals with a applying research of dynamic ion-beam mixing implanatation for promotingsurface hardness and contact fatigue characteristics of plungers in areo-engine pumps.It has been convincedthat the above new process could strengthen the plungers after the heat-treatments further.The results ofincreasing using lifetime of plungers are satisfactory.
