The tribological behaviour of PVD Chromium‐Nitride coated magnesium alloy AZ91hp was investigated in wear tests by variation of temperature and load. A combination of different investigation methods revealed information about the failure modes and wear mechanisms. The authors show that failure of the CrN‐AZ91 systems is due to the unsatisfactory load‐carrying capacity of the magnesium.
