Titanium alloys have poor tribological performance and there is considerable interest in producing wear resistant surfaces on titanium. An Fe-Ni alloy (IN 907) and a nickel alloy (HS 242) have been diffusion bonded to the high temperature titanium al

The effect of thermal exposure on the stability and effectiveness of carbon and TiBx coatings on σ(SM1240) fibre in a Ti–6Al–4 V metal matrix composite was studied. The results suggest that extensive loss of carbon coating starts only after cons

Rapid solidification (RS) of Ti-alloys containing B has been studied for more than a decade. Now, it has been realized that addition of B to Ti-alloy decreases the density and increases the tensile strength and the specific modulus. It has been repor
