摘要
一种含铪的镍基活性钎料对碳化物、氮化物、氧化物工程陶瓷具有满意的润湿性。该钎料重新熔化温度高于1190℃,不含硅、硼等脆性相形成元素,与镍基超极合金冶金相容性良好。钎料接头经表面钎涂或喷涂处理后可胜任高温工作条件。
A Hf containing Ni - base active brazing filler metal wets carbide, nitrde, oxide engineering ceramics very well. Its remelting temperature is higher than 1190 \\\\\ . It does not contain brittle phase forming elements such as silicon , boron etc. and is metallurgically compatible with Ni - base super alloy. The brazed joint after surfacebrazing coating or spraying can with stand elevated temperature environment.
