Claim 0:
1. A method for providing a part having a customized coating, comprising:
applying at least one metallic coating on a surface of a metallic substrate to provide a coated substrate; and
bonding the at least one metallic coating to the metallic substrate by a transient liquid phase bonding process to provide the part having the customized coating,
wherein the transient liquid phase bonding process comprises progressively heating the coated substrate to a bonding temperature,
wherein progressively heating the coated substrate to the bonding temperature comprises 1) heating the coated substrate to a first temperature that is lower than the bonding temperature to cause at least a portion of the at least one metallic coating to form at least one liquid interlayer, 2) heating the coated substrate past the first temperature to cause the at least one liquid interlayer to expand in thickness and dissolve a portion of a material forming the metallic substrate, and 3) heating the coated substrate to the bonding temperature to cause the at least one liquid interlayer to undergo an isothermal solidification process,
wherein heating the coated substrate to the first temperature causes a portion of the at least one metallic coating to melt by eutectic melting, and wherein the liquid interlayer is formed between the metallic substrate and an un-melted portion of the at least one metallic coating.
