Abstract
A quaternary alloying concept comprising the addition of 1-5 at% Fe to Al0.7Cr0.3 targets for cathodic arc evaporation at 550 °C is investigated regarding its influence on promoting singe-phase α-(Al,Cr)2O3 film growth. Based on detailed X-ray diffraction and transmission electron microscopy studies we can show that the α-phase fraction correlates with the incorporated Fe content and increases with increasing film thickness at the expense of the cubic phases.
