The Cr/Zr atomic ratios of the CrN/ZrN multilayer coatings were controlled, ranging from 1 to 2.5. The chemical composition of CrN/ZrN multilayer thin films was determined by a field emission electron probe microanalyzer (FE-EPMA). The phase composition of multilayer coatings was analyzed by a glancing angle X-ray diffractometer.
