The analysis of peculiarities of formation of the combined erosion coatings (CECs) on the structural and tool steels as well as nickel alloys is presented in this paper. New method of the CECs formation is proposed. It consists in applying an intermediate layer of copper between the base metal and the coating from wear-resistant alloys. Quasi-multilayer coatings formed by electroerosive alloying (EEA) in the sequences VK8 → Cu → VK8 on steels, VK8 → VK8 → Cu and VK8 → VK8 → Ni on nickel alloy KhN58MBUD are characterized by high quality factors. High microhardness (14200 MPa) is obtained on steel 45 and R6M5 by means of the EEA with composite electroerosive material 90% VK6 + 10% 1M.

Key words: electroerosive alloying, electrodes, combined coating, plastic deformation, structure, microhardness.
