Morphological and structural features of electrospark coatings
The morphology of the coatings has a significant effect on the tribological characteristics of the contacting bodies. Depending on the relief of the surface layers of the coatings, the resistance of the modified substrates to corrosion is dete rmined. It is known that the processes of friction and corrosion have a decisive influence on the performance of products. To reduce the influence of these processes, various protective coatings are used, including those formed by the method of electrospark alloying. The aim of th is work was to study the morphology and structure of electrospark coatings formed by layer-by-layer electrospark alloying. In the course of the studies carried out, it was found that these coatings are morphologically heterogeneous, with a large number of cracks and splats.
