Abstract: The surface modification of some materials(45, T8, 5CrMnMo, 3Cr2W8V) in fused borax bath added with aluminium oxide powders and reductant was Probed. The results showed that with proper salt composition and technical parameters, and B/Al ratio 1.3～3. 2 in salt bath, the boron atoms and aluminium atoms can co-diffuse in steels, thus an ideal B-Al co-diffusion layer can be obtained which contains ferro-boron phases and ferro-aluminium phases and ensues surface modification in steels.
