Tribo-Mechanical and Electrochemical Properties of Carbonitrided 316 Austenitic Stainless Steel by rf Plasma for Biomedical Applications
AISI 316 austenitic stainless steel was carbonitrided using rf plasma with purpose of using low-cost orthopedic implant materials in biomedical applications besides the manufacturing requests. The plasma treatment process was accomplished at low working gas pressure of 0.075 mbar in nitrogen-acetylene gaseous mixture. The plasma-processing time was fixed at 10 min while the plasma-processing power was varied from 450 to ... إقراء المزيد

Effect of DC-pulsed magnetron sputtering power on structural, tribological and biocompatibility of Ti–Zr–N thin film

Effect of DC-pulsed magnetron sputtering power on structural, tribological and biocompatibility of Ti–Zr–N thin film
The Dc. pulsed magnetron sputtering was employed to deposit Ti-Zr-N thin film on AISI 316 substrates. All the plasma parameters were kept to be constant except the plasma-processing power which was varied from 125 W to 250 W. The structure, tribological, electrochemical and biocompatibility properties of Ti-Zr-N films have been investigated. X-ray patterns confirmed the formation of solid solution phase ... إقراء المزيد

Effect of rf Plasma Carbonitriding on the Biocompatibility and Mechanical Properties of AISI 321 Austenitic Stainless Steel

Effect of rf Plasma Carbonitriding on the Biocompatibility and Mechanical Properties of AISI 321 Austenitic Stainless Steel
AISI 321 austenitic stainless steel was treated using rf plasma carbonitriding with the intention of use low-cost orthopedic implant material in biomedical applications. The treatment process was carried at low working gas pressure of 0.075 mbar in nitrogen-acetylene gaseous mixture to form a superficial carbonitrided layer. The samples were treated using rf inductively coupled at a fixed plasma-processing power of ... إقراء المزيد
