Characterization of delamination in titanium nitride coating on steel using acoustic microscopy
Wear resistance of Titanium Nitride (TiN) coating on steel is partly influenced by delamination located beneath the surface. Acoustic microscopy is particularly suited to analyze the subsurface defects. To examine the delamination defects introduced by sliding contacts in TiN coating on steel the Lamb wave velocities have been measured by V(z) curves and compared with the theoretically calculated velocities from dispersion curves.
