Abstract

With the overall objective to improve the service life and reliability of gas turbine engine bearings by increasing their corrosion resistance and rolling contact fatigue life a collaborative project under the EEC BRITE/EURAM programme has been initiated. The project is aimed at developing an ion implantation technique to implant bearing components with metallic species and to optimise the process particularly for applications where salt-water contamination of the lubricating oil might occur. Prior to implanting into bearing components, test specimens of M50 bearing steel implanted with Cr+ and Ta+ at several doses have been characterised by various techniques. This article reports on the implantation work, the RBS and NRA analysis for depth profiling and independent dose measurement, and the corrosion resistance measurements which have been performed in order to determine the optimum treatment.
