Resistance to fretting wear has been widely studied the last two decades. It has been shown that single TiN coatings on M2 HSS steels reduce the fretting damage about one order of magnitude and it is expected on the basis of theoretical considerations that hard multilayer coatings should present still greater resistance to wear. In the present paper hard modulated TiC/VC carbide multilayer coatings with lambda = 40 nm on M2 HSS steel substrate have been submitted to the fretting wear and the results have been compared with those for single TiC coating and for the M2 HSS substrate itself. The carbide coatings have been deposited with use of an indirect method invented in the Technical University of Łódź, Poland, the fretting tests have been performed in the Laboratory of Tribology and of Dynamic Systems of the Ecole Centrale in Lyon, France, and the results have been elaborated according to the new methodology developed in the latter. It turned out that the fretting wear of the multilayer coating was 25 times less than that of the M2 substrate, much less than that of the single TiC coating and 2.5 times less than that of the commercial TiN coating on the same steel.
