Methods are provided for repairing an engine component. In an embodiment, a method includes forming at least one layer of a first braze alloy mixture including about 40% by weight of a first base alloy material and about 60% by weight of a first braze alloy material, over a structural feature of the component. The first braze alloy material includes chromium, cobalt, tungsten, tantalum, aluminum, hafnium, carbon, boron, and a balance of nickel. A second braze alloy mixture is disposed over the at least one layer of the first braze alloy mixture, the second braze alloy mixture including 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. The component is then subjected to heat treatment, and may be further subjected to machining, coating and final inspection.
