摘要:
Diffusion bonding of aluminum alloy objects of different sizes and shapes may be greatly improved when the surface of the object is exposed to a thermal spray source which deposits fine metal particles on the surface. Rapid quenching of solidification occurs at the surface. Such treatment results in the formation of finer grains at the surface which enhances the strength of a diffusion bond.
