Ti-6Al-4V alloy possesses a remarkable combination of characteristics such as high special strength, superior corrosion resistance, stable high-temperature mechanical properties and good biological compatibility, which makes it find a wide variety of uses. However, its wear resistance is very poor.The origin of different types of wear failures and the surface abrasion resistance treatment technology of Ti-6Al-4V alloy has been reviewed through a detailed analysis in present paper. Adopting the surface engin...
