Abstract
A ceramic welding process, including projecting a ceramic welding powder including a mixture of refractory particles and fuel particles composed of a fuel material which is capable of being oxidized to form a refractory oxide against a surface in at least one stream of carrier gas which contains at least sufficient oxygen for substantially complete oxidation of the fuel particles, whereby sufficient heat is released for at least surface melting of the projected refractory particles and a ceramic weld mass is formed against the surface under the heat of oxidation of the fuel particles; and projecting at least one additional stream of gas selected from the group consisting of carbon dioxide, nitrogen, and a gas containing oxygen against the surface so as to form a substantially continuous gas curtain surrounding the at least one stream of carrier gas.
