Titanium nitride films were deposited by the methods of ion beam enhan
ced deposition (IBED), plasma chemical vapor deposition (PCVD) and ion
plating (IP). X-ray diffraction analysis was employed to determine th
e internal stress state of TiN film and 52100 steel substrate at both
sines of the interface. The effect of stress state on their bonding st
rength and tribological behavior was analyzed systematically, their we
ar and failure mechanisms were discussed in detail as well.
