A method and apparatus is disclosed for kinetic spray coating of substrate surfaces by impingement of air or gas entrained powders of small particles in a range up to at least 106 microns accelerated to supersonic velocity in a spray nozzle. Preferably powders of metals, alloys, polymers and mixtures thereof or with semiconductors or ceramics are entrained in unheated air and passed through an injection tube into a larger flow of heated air for mixing and acceleration through a supersonic nozzle for coating of an article by impingement of the yieldable p...
[ What is claimed is:] [1.] A method for applying to an article a coating of particles including particles having a particle size in excess of 50 microns, the coating being formed of a cohesive layer of the particles in solid state on the surface of the article, the method comprising:mixing, into a gas, particles of a powder of at least one first material selected from the group consisting of a metal, alloy, mechanical mixture of a metal and an alloy, and a mixture of at least one of a polymer, a ceramic and a semiconductor with at least one of a metal, ...
