Abstract

In a process for diffusion coating a metal object with another metal or with a non-metal, a halide or other dissociable compound of the element to be diffused together with the element in powder form are provided on the surface to be coated, said element being Cr, Mn, Ni, Co, Cu, Zn, Cd, Nb, Ta, V, Ti, Zr, Be, Ce, Th, Si or B. Other elements, preferably metallic, capable of reducing the dissociable compound and possibly capable of entering into the coating may also be incorporated. In the examples, steel is diffusion coated (1) with Cr using a composition containing CrCl2, Cr, MgO and Mg, (2) with Cr-Al using a composition containing CrF2, Cr, Al2O3 and Al, (3) with Cr using a composition containing CrCl2, Cr, MgO and Ca, (4) with Cr-Si using a composition containing CrF2, Cr, MgO and Si, and (5) with Cr-Ni-Si using a composition containing CrF2, Cr, NiF2, Ni, MgO and Si. Other metals which may be coated are Fe, Ni, Co, Mo, W, Ti, Zr, Nb and Ta. Diffusion is effected by furnace heating or by induction heating, optionally in the presence of reducing or inert gases, e.g. He, A, H2, N2 or NH3, or reactive gases, e.g. I2, Cl2 or volatilized halides. Specification 915,089 is referred to.
