Microwave process for forming a coating

A process for forming a coating on a surface of a substrate (14), in which the heating source for the coating process is microwave radiation (18) so that heating of the coating material is selective and sufficient to melt and bond the coating material to the substrate (14) without excessively heatin...

Beschreibung
Zusammenfassung:	A process for forming a coating on a surface of a substrate (14), in which the heating source for the coating process is microwave radiation (18) so that heating of the coating material is selective and sufficient to melt and bond the coating material to the substrate (14) without excessively heating the substrate (14). The process entails forming a coating material (10) containing powder particles (12) that are sufficiently small to be highly susceptible to microwave radiation (18). The coating material (10) is applied to a surface of the substrate (14) and subjected to microwave radiation (18) so that the powder particles (12) within the coating material (10) couple with the microwave radiation (18) and sufficiently melt to form a coating (28) on the substrate (14) surface. The microwave radiation (18) is then interrupted to allow the coating (28) to cool, solidify, and mechanically bond to the substrate (14).
