Research of plasma impact on migration of silicon in ceramic substrates prepared on the basis of MgO

Abstract

© Published under licence by IOP Publishing Ltd. To solve a number of problems in metallurgy and construction, it seems promising to obtain physical and chemical methods of coatings on ceramic materials. In particular, the plasma-arc method makes it possible to obtain coatings with a thickness of 100-200 μm from oxides and carbides. To solve this problem, it is necessary to investigate the interaction processes of the ceramic substrate and the coating that occur during plasma spraying. In this work, ceramics with different Si contents with a deposited Al2O3 coating were selected as the object of study.
