Paper Title:
Friction/Wear Properties of Magnetron Sputtered TiB2-TiN Composite Films on Biomedical Metallic Titanium Alloy
  Abstract

TiB2-TiN composite films/SiC films (SiC films as interlayer) were deposited on biomedical titanium alloy (Ti6Al4V) through magnetron sputtering technique. The friction/wear behaviors of the TiB2-TiN composite films under Kokubo simulation body fluid (SBF) were investigated. The results show that as sliding against Si3N4 ball (4 mm in diameter) at 200g load, the TiB2-TiN composite films exhibited the superior friction/wear properties with the friction coefficient of 0.22, the special wear rate in the magnitude order of 10−6 mm3 m−1 N−1 together without interface delaminating. It was found that the films exhibited navel adhesion to Ca and P elements in Kokubo SBF. The present results demonstrate the possibility of developing the surface modification procedure of combining superior wear resistance and good osseointegration for application of orthopaedic implants.
