Ⅰ. PRINCIPLE The surface modification technology is based on the principle of thermal diffusion coating process. TD is short for Thermal Diffusion. By immersing tools or parts into fused salt bath. Carbon in the steel substrate diffuses from the tools to combine with carbide-forming elements such as vanadium(V), niobium(Nb), chromium(Cr), ...
