-- 3 NI-TI-CR NEAR TERNARY EUTECTIC ALLOY FOR GAS TURBINE COMPONENT REPAIR

摘要

Quasi-ternary eutectic alloys of Ni, Ti, Cr are described as having a relatively low melt temperature of approximately 1230 ° C. or less suitable for welding cracks in turbine blades and vanes without fear of substantial cracking during the repair process. Such alloys are suitable for low temperature joining or repair of turbine blades, which are typical turbine blades and vanes without foreign elements to adversely affect the mechanical characteristics of the repaired component or to lower the melting point of the repaired material. This is because it includes the same components as. The exclusion of boron eliminates the formation of brittle boron compounds that are detrimental to the features of the repair or seam.
