Patent ID: 7824510

Claim:
A method of repairing an engine component, the method comprising the steps of: forming at least one layer of a first braze alloy mixture over a structural feature of the component, the first braze alloy mixture comprising: about 40% by weight of a first base alloy material, and about 60% by weight of a first braze alloy material, the first braze alloy material comprising: between about 6.7% and about 9.2% by weight chromium; between about 9.7% and about 10.3% by weight cobalt; between about 3.7% and about 4.7% by weight tungsten; between about 3.3% and about 6.3% by weight tantalum; between about 3.6% and about 5.2% by weight aluminum; between about 1.3% and about 4.0% by weight hafnium; between about 0.02% and about 0.06% by weight carbon; between about 1.0% and about 3.2% by weight boron; and a balance including nickel, disposing a second braze alloy mixture over the at least one layer of the first braze alloy mixture, the second braze alloy mixture comprising: between about 50% and about 60% by weight of a second base alloy material, and between about 40% and about 50% by weight of a second braze alloy material; and subjecting the component to a heat treatment to melt the first braze alloy mixture and the second braze alloy mixture and to flow at least a portion of the first braze alloy mixture into the structural feature.
