Abstract
A method is disclosed for fabricating a low cost, elevated-temperature resistant part with a serrated surface and elevated-temperature structural properties similar to (within fifty percent (50%)) a superalloy material comprising the steps of: forming a master tool having the desired serrated surface; electro-forming the elevated-temperature resistant part by depositing three alloying elements comprising nickel, cobalt and manganese onto the master tool in the amounts of about 60%-70% nickel, 40%-30% cobalt and 0.05%-0.10% manganese; and separating the elevated-temperature resistant part from master tool.
