ResumoTiAlN/interlayer coatings on drills were investigated for the coating characteristics and drilling performance. The interlayers investigated include TiN, TiAl, and electroless Ni-P. The coating characteristics and wear behaviour of the coatings during a drilling test were studied with XRD, XPS, and SEM. It was found through XPS that a greater binding energy of the coating elements leads to a longer tool life for the drill. The factors which affect the drill performance also include the bonding behaviour between coating and interlayer.
