Effects of Heat Treatment and Shotpeening on Sliding Wear Behavior of Titanium Biomedical Implant Materials

Abstract

quotTitanium and its alloys have very attractive properties that enable them to be used in the newlinefields of aero space, biomedical, marine and also in many corrosive environments. newlineTitanium alloys such as Ti-6Al-4V and Ti-6Al-7Nb are extensively used in orthopedic newlineapplications due to their superior biocompatibility, corrosive resistance, and better newlineosseointegration with good mechanical strength. These alloys have high coefficient of newlinefriction and poor abrasive wear resistance which results in the wear of the implant during newlineits fixation in the body. Implant wear is a common phenomenon which results due to high newlinefriction between artificial implant materials when in contact with natural bone which is newlinemuch higher than healthy and natural joints that can withstand cyclic loads acting on newlinethem.quot newline newline
