Using the resistance to environment bond membrane, repairs the part the manner which and as a result was obtained and it repaired is exposed

摘要

PROBLEM TO BE SOLVED: To give advantages of extended part life and increased mending property to parts mended by an embodiment of this invention.;SOLUTION: These mended parts include parts used for engine operation having a base metallic substrate forming a residual base metallic substrate with reduced thickness by removing one part with thickness of about 1-3 mm, and an overlay bonding coat. The mended parts include a low-growth and environment-resistant bond membrane containing alloys having aluminum content of about 10-60 atom% applied to the residual base metallic substrate, and growth of the environment resistant bond membrane into the substrate is smaller than that of a conventional bonding coat, the residual base metallic substrate with thickness smaller than about 1-3 mm is removed at the next part mending time.;COPYRIGHT: (C)2005,JPO&NCIPI
