Cross Section of TiN Coating
Since the substrate is titanium and the transition layer gradually changes from
pure titanium to TiN the bond between layers is ionic rather than adhesive as it is
for other substrates or coatings. Ionic bonding is such that the surface bond is
much stronger than is the case of an adhesive bond.
