A nickel base repair alloy comprises a blend of about 40 to 60 wt % of a first nickel based braze alloy containing boron, about 15 to 35 wt % of a first nickel based filler material, and the remainder consisting of a blend of a second nickel based filler material and a low melting eutectic braze nickel based alloy.

Nickel alloy for repairs

A process for repairing cracks in a workpiece, such as a turbine engine component, comprises the steps of: providing a workpiece having a crack to be repaired; applying a nickel or cobalt base alloy material to a root of the crack in an amount sufficient to fill a portion of the crack; subjecting the workpiece with the nickel or cobalt base alloy material to a first heat treatment at a temperature in the range of from about 1950 to 2300&#xb0; F. for a time period in the range of from about 5.0 to 30 minutes; applying a weld material to the crack; and subjecting the workpiece with the weld material to a second heat treatment.

Dual process nickel alloy crack repair

Systems and methods for forming components with thermal barrier coatings are provided. In this regard, a representative method includes: providing a component having a first side and an opposing second side; and using a preformed mask to obstruct vapors from being deposited on the second side of the component while moving the component relative to the vapors such that the vapors form a thermal barrier coating on the first side of the component.
