Repair of coatings and surfaces using reactive metals coating processes

摘要

This invention pertains to the repair of parts comprising metals, and surfaces and coatings of these parts using reactive metals coating processes. Processes such as chemical vapor deposition (CVD), physical vapor deposition (PVD), plasma spray, and reactive coating (boronizing, carburizing, nitridizing, carbonitridizing, etc.) are known for producing durable coatings or surfaces on metal parts, and the present invention provides a means to spot-repair these coatings or surfaces without excessive buildup of repair material on undamaged areas.
