Abstract: The plasma sprayed ceramic coatings Cr2O3and Al2O3in sliding contact with steel were studied by both block-on-ring arrangement (tester T 05) and deep-drawing process. The friction coefficient and wear of these coatings were measured at dry friction conditions and with lubricant at utilization of tester T 05. For different types of die rings (with and without ceramic coatings) the punching forces were measured during deep-drawing process.
