Title:
HIGH-TEMPERATURE SINGLE CRYSTAL ALLOY BRAZING MATERIAL AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/232030
Kind Code:
A1
Abstract:
A high-temperature single crystal alloy brazing material, comprising alloy powder and a binder, wherein the alloy powder comprises the following components by weight: 8%-18% of Cr, 3%-12.0% of Co, 1%-6% of W, 1%-6% of Ta, 2%-6% of Al, 0.5%-4.2% of Mo, 1%-5% of B, no more than 5% of Hf, and no more than 3% of Re, with the remainder being nickel and inevitable impurities. The high-temperature single crystal alloy brazing material has a low brazing temperature and a short welding process duration, so that thermal damage to a single crystal base material can be effectively reduced, and production efficiency is improved. The present invention further provides a high-temperature single crystal alloy brazing method.
