Abstract
A technology was developed for the formation of a multilayer composite coating obtained by the sub – and supersonic plasma spraying method based on Al, Ti, Ni, and Mo. The results of the investigation of a coating of Al-Ti-Ni-Mo powder are deposited by subsonic plasma deposition on a steel substrate followed by the application of an anticorrosion coating from a paint coating material (PCM) of the CINEP brand, which is protected by the supersonic spraying powder Al-Ti-Ni-Mo. This coating layer is designed to protect the anticorrosive layers of the main multicomponent coating of products, which can be subjected to external mechanical stress during operation. It is shown that the resulting composite coating is sufficiently strong and withstands strains in the zone of elastic deformation of the matrix. Carried out corrosion tests showed a high resistance of these coatings.
