Abstract

Processes of supersonic blasting for producing thin metal coatings and of cold spray for producing thick coatings by solid metal particle jets are based on the particle plastic deformation. Extensive plastic deformation of accelerated metal particles at the surface roughness was observed. The possibility of stimulation of metal particle deposition by the substrate and coating blasting by ceramic particles was experimentally confirmed. The process of thick coating creation by the mixed metal-ceramic powder supersonic jet is presented.
