Abstract

The paper presents the results of the application of the vacuum-arc spraying method to obtain coatings on the structural material. Experiments were carried out on the vacuum-arc accelerator VАА-1. The processing parameters were selected in order to achieve the most effective result. The structure and physical and mechanical properties of the surface layer of stainless steel after deposition of copper coatings have been studied by means of x-ray spectral analysis, scanning electron microscopy and metallography. The presented results are an intermediate stage in a series of experiments to obtain coatings by this method. It is established that there is a decrease in the microhardness of the surface layer due to the formation a coating of copper. There is also observed a sealing and smoothing of the surface of the test sample, which should lead to improved performance properties of the material. In addition, deposition by this method leads to good continuity and adhesion of the coating to the substrate.

Keywords: vacuum-arc, plasma spraying,copper coating, deposition,smoothing, microhardness.
