Abstract: Paper presents features of plasma alloying of Cu-based materials with Ti-Cr, Ti-Cr-Ti-Nb, Ti-Cr-Ti-Zr, Ti-Cr-Ti-ZrO coatings in different regimes of the QSPA Kh-50. Targets were made from copper samples covered of multilayer PVD coatings have been deposited within a Bulat-type facility. Prepared targets were irradiated with powerful plasma streams with energy loads achieved 0.6 MJ/m² and the pulse duration of 0.25 ms. Influence of plasma impacts on modification different copper alloys has been analyzed. Mechanisms of modification of thin multilayered coatings mixed with Сu substrate in a liquid phase under the plasma processing are evaluated.
