BRAZE ALLOY FOR HIGH-TEMPERATURE BRAZING AND METHODS FOR REPAIRING OR PRODUCING COMPONENTS USING SAID BRAZE ALLOY

摘要

the present invention is a high temperature braze Ni-based, Co-based or Ni-Co-based braze alloy (1) and also a method for manufacturing or repairing the part 7 of the modular structure and the braze alloy for It relates to a method for repairing a damaged part (7) made of a single crystal or unidirectional solidified superalloy with (1). The surface of the particles of the braze alloy nano claim including m first metallic powder component having a particle size in the range 2 and the second metallic powder component having a particle size in the micrometer range (3), and the second powder component (3) is the first powder component (2) is coated with a thin particles, the braze alloy (1) of the grain boundary stabilizing elements as an alloying element further comprising. Moreover, the melting point lowering agent may be present in an amount in a conventional or commercially significant increase in proportion to the braze alloy (1). The melting temperature and the probability of re-crystallization of the braze alloy (1) is reduced enough, both glass. ;
