BLENDING RATIO DECISION METHOD FOR Ni-BASED MATERIAL BLENDED WITH REPAIR MATERIAL FOR DIFFUSION SOLDERING AND REPAIR MATERIAL FOR DIFFUSION SOLDERING

摘要

PROBLEM TO BE SOLVED: To provide a method which enables a simple decision of a blending ratio of a Ni-based molten alloy powder to a Ni-based unmolten alloy powder blended with a repair material for diffusion soldering.;SOLUTION: A blending ratio decision method for a Ni-based material blended with a repair material for diffusion soldering of the embodiment includes a process for deciding a target value of a solidus line temperature requested for the repair material, a process for selecting a Ni-based molten alloy powder and a Ni-based unmolten alloy powder blended with a repair material, a process for calculating a solidus line temperature after the diffusion heat treatment of a blending agent of the Ni-based molten alloy powder and the Ni-based unmolten alloy powder at a plurality of blending ratios by means of thermodynamic calculation, a process for plotting a calculated solidus line temperature after the diffusion heat treatment with the parameter of a value calculated from a predetermined relational expression to acquire an approximation curve, and a process for deciding the blending ratios of the Ni-based molten alloy powder and the Ni-based unmolten alloy powder by using the approximation curve and a predetermined relational expression with the index of a target value of a solidus line temperature after the diffusion heat treatment.;COPYRIGHT: (C)2015,JPO&INPIT
