Sputtering of Titanium in Co-Cr-Mo Alloys for Orthopedic Implant Materials

Abstract:

Sputtering process of titanium have been carried out to improve the hardness and wear resistance of the Co-Cr-Mo alloy for orthopedic implant material. The CoCrMo alloy was synthesized by melting process with addition of Cr₂N powder into melts to define the high Cr and high N contents. The solid Ti target was sputtered by argon gas and coated into the CoCrMo substrate at temperature of 200 °C for 2, and 4 hours in the nitrogen gas environment. Characterization was performed to the specimen of CoCrMo ingot before and after sputtering process by microstructure, hardness, corrosion and wear resistance tests. Synthesis of the alloy produced dendrite structure ingot. The hardness, the wear resistance and the corrosion resistance in the simulation body fluid increased after sputtering process due to the formation of oxide thin layer in surface of the alloy.
