Article Preview

A niobium modified layer on Ti-6Al-4V surface was obtained by means of the plasma surface alloying technique. The oxidation behavior of the modified layer was investigated and compared with Ti-6Al-4V at 700°C~900°C for 100h. Composition and microstructure of Ti-6Al-4V and the modified layer after oxidation at 900°C for 100h were analyzed using XRD and SEM respectively. The experimental results showed the oxidation behavior of Ti-6Al-4V at 900°C for 100h was obviously improved after the niobium alloying process.
