Open the CIPO recordAbstract From the Canadian patent
A method for producing a metallic interface suitable for overlaying Consists of exposing the area of an alloy combination to be overlayed to a temperature above its lower critical until an element reduced zone arises. This element reduced zone more easily accepts element diffusion that takes place during overlaying. Accordingly an improved interface, one that is more ductile and less prone to cracking, is produced.
