Structural and Phase State of the Material between the Ceramic Layer and the Metallic Substrate Formed by High-Speed Jet of Powder

Abstract

In the present study, a new multi-chamber detonation sprayer (MCDS) was used to deposit Al2O3 coatings on titanium and carbo steel substrates. SEM, TEM, and XRD analysis of the layer between the coating and substrate revealed the presence of an intermetallic compound that improves coating properties and is conducive to the relaxation of stresses generated during spraying.
