Oxidation behavior of a high Si content Al–Si composite coating fabricated on Ti–6Al–4V substrate by mechanical alloying method

An Al–Si coating was successfully fabricated on Ti–6Al–4V alloy substrate by means of mechanical alloying method. The coating was prepared with Al–33.3 wt% Si powder mixture. The coating had a composite structure and its thickness was about 350 μm. The mass gain and the oxidation rate of the substra...
