Plasma Coatings for Protection Against Hydroabrasive and Cavitation Wear

Abstract

The results of research work on the application of coatings designed to protect the working surfaces of machine parts and mechanisms operating under conditions of hydroabrasive and cavitation wear are presented. Coatings were produced by supersonic atmospheric plasma spraying of powder materials using air as a plasma gas. The experimental list of materials was chosen taking into account the experience of the authors in protecting the details of the propulsion and steering complex of river vessels using coatings applied by subsonic thermal plasma flows.
