Abstract
The invention discloses a hard soldering method of high volume fraction SiC particle-reinforced Al matrix composite and a kovar alloy dissimilar material, relating to a hard soldering method of a dissimilar material. The invention solves the problem that welding cost is high because the existing hard soldering of the dissimilar material needs metalizing treatment. The method of the invention comprises the following steps: after cleaning master batches and foil-shaped brazing filler metal, putting the foil-shaped brazing filler metal between the master batches, and then putting into a vacuum furnace for soldering to finish hard soldering of the master batches. The method of the invention obtains soldering seams with compact issue and forms firm metallurgical bonding. The invention does not need to carry out metallization processing on the master batch, thus lowering welding cost.
