The critical parameters for the structural stability of physical vapor deposited TiN film on (112̄0) sapphire were investigated by analyzing the adhesion strength and failure mechanism through in situ observations of the fracture sequence during scratch tests and static normal indentation. TiN was deposited by arc ion plating on (112̄0) sapphire, and the thickness of the TiN film was controlled t...
