Abstract
The article presents the results of microhardness research of wear-resistant plasma coatings from
high-chromium powder material after the influence by high-frequency currents. In contrast to the
initial structure, the microhardness distribution according to the layer depth becomes almost
uniform, although its level remains on average values with the initial one. The comparative wear-
resistance tests under friction-sliding conditions of samples with initial structure and the structure
obtained after the induction heating influence demonstrate the absence of wear-resistance increase.
