ABSTRACT Brazing using arc-sprayed coatings was investigated for appl i cat ion to non-oxidat i on copper brazing. It was found that the more porous sprayed coatings have an excel lent brazeabi I i ty. This newly deve I oped joining method is more suitable than conventional methods for brazing complicated parts. We have appl ied this method to fabricate a torque converter for practical use. INTRODUCTION Brazing is now applied to a wide variety of automotive parts, from smaller parts to larger ones such as heat exchangers. Among al l brazing methods, non-oxidation copper brazing is popular since this brazing method does not require flux. One of the typical automotive Parts join- ed by this method is the pump impeller of a hydraulic torque converter for an automatic transmission. There, a number of blades are joined by non-oxidation copper brazins. A typical brazing method for these blades is preplaced brazing. In preplaced brazing, a brazing f i l ler copper metal is preformed to copy the blade outline, or a paste copper brazing metal is set on the top en
