Method for forming a carbide layer on the surface of an iron or ferrous alloy article |
| abstract |
A method for forming a carbide layer of a metal selected from Ti, Zr, Hf, V, Nb, Ta, Mo and N or mixtures thereof on the surface of an iron or ferrous alloy article in a powdery treating material comprising packing said article in the mixed powders of a tetrafluoroborate and said metal and heating said article within said mixed powders, thereby forming a very hard carbide layer of said metal on the surface of said article. The method of this invention can be carried out without employing a nonoxidation atmosphere and can improve greatly the wear resistance of iron and ferrous alloy articles. |
