Effect of Si3N4 Addition on the Mechanical Properties, Microstruc-tures, and Wear Resistance of Ti-6Al-4V Alloy

Ruihua HU , Montasser M.Dewidar , Hyo-Jin KIM , Jae-Kyoo LIM , null

In order to improve the wear resistance of Ti-6Al-4V, different amounts of Si3N4 powder were added into the alloy powder and sintered at 1250℃. Porous titanium alloy with higher wear resistance was successfully fabricated. At sintering temperature, reaction took place and a new hard phase of Ti5Si3 ...
