Abstract:

In this paper, the effects of aluminizing agent composition, filler particle size, process parameters and adding impinging particle into aluminizing agent on the thickness of aluminizing layer were investigated. The mechanism of the significant reduction in aluminizing temperature using aluminizing agent was analyzed. The results indicate that the aluminizing temperature can be reduced to 500°C through mechanical energy aided aluminizing. The mechanical energy aids to improve the surface adhesion probability of Al powders on the specimen surface, increases the chemical activity and adhesion strength of Al powders, thus the aluminizing temperature is greatly reduced.
