Titanium Alloy Bar Suitable for Highly Efficient Wear-Resistance Treatment 950940

To give the wear-resistance to titanium intake valves by simple oxidation treatment, oxidation condition and microstructure of Ti-6Al-4V bars were studied. The wear test using a valve simulator shows that the wear of the face oxidized at 820°C for 1 and 4h in air is superior to that of ferrous valves. The best micro-structure of Ti-6Al-4V bar is an acicular structure with the prior β grain size of 30 to 60 μ m in average, which prevents distortion during the oxidation treatment and has excellent mechanical properties.
