摘要：
The solid state diffusion bonding process is performed using a liquid film protection (LFP) method for AA8090 aluminum alloy in contrast to the more costly vacuum environment. After chemical etching and prior to bonding, aluminum sheets were immersed in dehydrated alcohol to isolate surface from air. Two sheets are then joined with a special clamp to form a specimen which is press-deformed and heated in a salt bath. Protecting liquid film completely volatilizes on heating to bonding temperature thus keeping bonding surface free from oxidation. Effectiveness of the LFP-method is demonstrated in various combinations of process parameters. The contact ratio, in particular, is an important index for bonding strength.
