APPLICATION OF SINTER-BRAZING

It is well-known that brazing of sintered parts is very difficult because of absorption of molten brazing alloy into the porous body. Our special brazing alloy has overcome this difficulty and made it possible to sinter and to joint two green compacts simultaneously in a sintering furnace. This sinter-brazing process enables us to make such complicated parts as conventional P/M technics can not achieve. In this paper, two examples of automobile application of these sinter-brazed parts are discussed. One is the rotor of compressor for car-airconditioner, and the other is the side-plate of oil-pump for power-steering. The rotor has a hollow groove inside to reduce its weight. The side-plate has a complicated oil-tunnel in it. The sinter-brazing is the most suitable manufacturing method to make such complicated configurations as cavities and passages. Due to the fixed dimensions of green compacts, the accuracy of the assembled parts is better than that of parts assembled after sintering.
