CHARACTERIZATION OF TiAlN COATINGS DEPOSITED BY SPUTTERING USING UNBALANCED MAGNETRON SOURCES AND CATHODE ARC EVAPORATION ON AISI D2 STEEL

The investigation was performed on commercially available tool steel AISI D2 of Uddeholm Company under the trade name Sverker 21, which was a substrate for applying the physical vapour deposition (PVD) TiAlN coatings. The investigated coatings were deposited by sputtering using unbalanced magnetron sources– CC800 (CemeCon) at Jozef Stefan Institute (Ljubljana, Slovenia) and cathode arc evaporation technique (BAI 1200) in Balzers (Kapfenberg, Austria). The use of hard ceramic coatings deposited by PVD onto tool steels can result in significant improvements in tool life over the uncoated materials. Several fundamental properties of the deposited coatings were investigated. The following laboratory tests were performed: microhardness measuring, nanoindetation test, scratch test, investigation of adhesion, roughness measuring. Results of scanning electron microscopy and glow discharge optical emission spectroscopy (GDOES) depth profile results are included as well.
