Intense oxidation of sputtered metal happens to be at electric-arc sputtering, due to oxygen, contained in the air, it leading to drastic reduction of the content of alloying elements in the coating.This work contains a method of evaluation of micro-hardness of the particles of the coating, deposited with pulsating air supply into the area of electrodes melting by introducing an additional element into the spraying head of the electric-arc metallizator Also performed was estimation of the amount of non-metallic inclusion. Also included are the results of alternations in particles micro-hardness, depending upon the frequency of pulsations at EAM with application of a pulsating spraying jet.
