LOW TEMPERATURE PROCESS OF APPLYING HIGH STRENGTH METAL COATINGS TO A SUBSTRATE AND ARTICLE PRODUCED THEREBY

摘要

A LOW TEMPERATURE PROCESS OF APPLYING HIGH STRENGTH METAL COATINGS TO A SUBSTRATE AND ARTICLE PRODUCED THEREBY A method of applying a dense (about 99% of theoretical density) metal coating to a substrate using a converging/diverging nozzle to nebulize metal into a plume with uniform mass and thermal fluxes and a metal droplet size distribution of about 5-15 microns. Coatings may be deposited on substrates which thermally degrade at temperatures far below the melting point of the metals deposited thereon. Coated articles having strong mechanical bonds are also disclosed.
