ABSTRACT:
Diffusion aluminizing with chromium or silver chloride, bromide or iodide that is not significantly soluble in or reactive with water. Hydrogen can be excluded from diffusion aluminizing atmosphere when aluminizing maraging steels or other substrates sensitive to hydrogen. Aluminized iron powders can be boronized to increase their exothermic heat upon exposure to air after leaching out aluminum.
