method to utfu00e4lla hard layers on cemented carbides with bu00e5gfu00f6ru00e5ngning and cathode with ti3sic2 as main component

摘要

A method of producing hard wear resistant layer with improved wear resistance. The method is a reactive arc-evaporation based process using a cathode including as main constituent at least one phase of a refractory compound Mn+1AXn (n=1, 2 or 3), wherein M is one or more metals selected from the groups IIIB, IVB, VB, VIB and VIIB of the periodic table of elements, A is one or more elements selected from the groups IIIA, IVA, VA and VIA of the periodic table of elements, and wherein X is carbon and/or nitrogen.
