Abstract

Transmission electron microscopy, X-ray diffraction, Rutherford backscattering, proton elastic resonance, and other methods have been employed to study the defect substructure and the phase and elemental composition of coatings of stainless steel SUS316L applied onto a substrate of low-carbon steel SS400 using pulsed plasma detonation technology. Dense coatings 120-620 μm thick were produced using high-speed (3-8 km/s) high-temperature (4000-30000 K) pulsed (4-6 Hz) plasma jets. During the deposition of a plasma-detonation coating, structural and phase transformations were found to occur in both the coating and the substrate. The phase composition of the applied coating differs from that of the starting powder, namely, the surface layer is saturated with light impurities (oxygen and carbon) and depleted of alloying elements (Ni, Cr, Mo); significant part of the γ phase transforms into the α phase; mutual penetration of the elements composing the coating and the substrate occurs; a transition region is formed in the substrate, which is characterized by a fine-grained structure with a high density of dislocations and an enhanced (relative to the initial state) volume fraction of carbide particles. Conditions that ensure the best cohesion between the coating and substrate have been determined. Explanation of the effects observed is given.
