Surface Plasma Molybdenized Burn-Resistant Titanium Alloy

Abstract:

Article Preview

Conventional titanium alloy may be ignited and burnt under high temperature, high pressure and high gas flow velocity condition. In order to avoid this problem, a new kind of burn-resistant titanium alloy-double glow plasma surface alloying burn-resistant titanium alloy has been developed. Alloying element Mo is induced into the Ti-6Al-4V substrate according to double glow discharge phenomenon, Ti-Mo binary burn-resistant alloy layer is formed on the surface of Ti-6Al-4V alloy. The depth of the surface burn-resistant alloy layer can reach about 100 microns and alloying element concentration can reach 59%. High energy laser ignition experiments reveal that the ignition temperature of alloyed layer with Mo concentration about 10% is about 200°C higher than ignition temperature of Ti-6Al-4V.
