Abstract

Increasing requirements on high speed and dry cutting applications open up new demands on the quality of cutting tool materials. In this study, we evaluated the effect of Cr additions on the properties of Ti(Al)N/Cr(Al)N multilayered films deposited be magnetron sputtering. In particular, we studied the high temperature tribological properties and the cutting performance in real service drilling tests and compared the results with a monolayer Ti0.47Al0.46N reference film. Dry sliding experiments were performed using a pin-on-disc tribometer at room temperature and at 650 ºC with Al2O3 balls as counterparts. The drilling performance of the coatings was evaluated at cutting speeds in the range 50-200 m/min. Wear of the drills in different zones (chisel edge and flank edge) was mapped after each 15 holes.
