Zr基ろうによる工業用純チタンのろう付

抄録

The work in this paper was designed to develop the brazing filler metal for commercial pure titanium (CPTi) from the viewpoint that the filler metal is composed of simpler alloy system having lower melting point and sufficient wettability comparing with Ti-based filler metals which have been developed so far. In this work, we investigated the Zr-based eutectic system filler metal and the wettability. The results of this work show that the Zr-47Cu filler metal allows brazing of CPTi below the α-β transfomation temperature and provides us with the joint possessing sufficient mechanical properties and corrosion resistance.
