Ni-Ti-Cr ternary near-eutectic alloy for repair of gas turbine parts

摘要

A Ni, Ti, Cr ternary system that has a relatively low melting temperature of about 1230 ° C. or less and is suitable for fusing cracks in turbine blades and blades without the inherent risk of cracking during the repair process A near-eutectic alloy is described. Such an alloy is suitable for cold joining or repairing of turbine blades because it contains the same composition as typical turbine blades and blades, lowering the melting point of the material being repaired or being repaired This is because there are no external factors that adversely affect the mechanical properties of the. The exclusion of boron eliminates the formation of brittle boron compounds that are detrimental to the repair or seam characteristics.
