BRAZING FILLER METAL FOR JOINING TI AND TI ALLOY AND ITS FORMING METHOD

摘要

PURPOSE:To eliminate the effect of a gas and to improve the corrosion resistance of a joining part by using the Al-Pd alloy or Al-Pt alloy containing Pd or Pt of specified amt. as the insert alloy for joining. CONSTITUTION:For the insert stock for joining the Al-Pd alloy or Al-Pt alloy containing 0.1-5% Pd or Pt is used. In order to form this insert stock the joining face 2 of the material 1 to be joined subjected to working and ultrasonic cleaning is subjected to sputter etching by the Ar ion generated from an Ar ion gun 5 to form in the joining face 2 or a cleaned face 3 is provided by removing sticking oxide film, adsorption gas and impurities. Then, the Al alloy insert layer 4 for joining is offered to joining after providing it by a magnetron sputter device 6 on the cleaning face 3 provided on the material 1 to be joined inside the same container 7.
