Abstract

The development of an effective ceramic conversion treatment of TIMETAL LCB (Ti-6.8Mo-4.5Fe-1.5Al) has been investigated. Various characterisation methods were used to analyse samples in order to identify the best process conditions including SEM, EDX, XRD, GDS, micro-indentation and scratch testing. The results show that the tribological properties of the TIMETAL LCB alloy have been significantly enhanced by the new ceramic conversion treatment specifically developed for beta alloys. The improved friction and wear properties can be attributed to the low-friction TiO2 surface layer supported by an oxygen diffusion hardened case up to a depth of ∼70μm.
