Abstract
Research evidence of plasma parameters effect when spraying aluminum oxide powder, causing the porosity and electrical resistance of the coating is offered in the article. A mathematical model of the coating effect dependence on spray coating modes, e.g. plasmotron distance to underlay surface, current strength and hydrogen consumption is proposed. Positive cor-relation between the porosity and the electrical resistance of the coating is shown.
