•Hardness of 50 GPa for AlTiN/AlCrBN multilayer films•Increased hardness as a result of increased number of layers•Reduced compressive stresses with decreasing sub layer thickness•Enhanced wear resistance of AlTiN/AlCrBN multilayer films
AlTiN/AlCrBN multilayer films were synthesized by means of cathodic arc evaporation. The influence of the individual layer thicknesses on mechanical and tribological properties was systematically investigated and compared with AlCrBN single layer films. AlCrB targets with 10 and 20 at.% B, respectively, were used in combination with AlTi targets, having an Al/Ti ratio of 1. The multilayer films exhibit enhanced hardness and significantly reduced residual compressive stress together with improved wear resistance compared to AlCrBN single layer films.
