喷丸是用一种小而坚硬的弹丸高速撞击金属表面的一种冷加工方法。它已成功地用于喷丸成形、喷丸校正、喷丸强化、喷丸装饰等。最近,我们又将喷丸加工应用于气密喷丸和透气性表面喷丸,收到了可喜的效果。一、气密喷丸在我厂某项科研工程中,有一个需要高度真空的铝合金零件,要求保持8小时以上不渗漏,其外形尺寸如图1所示。在制造过程中, Shot peening is a cold working method that uses a small but hard shot to hit a metal surface at high speed. It has been successfully used for shot peening, shot peening, shot peening, shot peening and more. Recently, we have applied the shot peening to the gas-tight shot blasting and the breathable surface shot peening and received encouraging results. First, the gas-tight shot in our plant a research project, there is a need for a high degree of vacuum aluminum parts required to maintain more than 8 hours without leakage, its dimensions shown in Figure 1. In the manufacturing process,
