Abstract
To produce resisting metal coatings containing at least one brazing metal surfaces formed of titanium or another refractory metal having at least one volatile halide, a coating of this halide of the brazing metal is applied to this surface, this halide being stable in the isolated state and when applied to the surface, the halogen of the said halide being able to form the volatile halide with the refractory metal; the surface thus coated is heated to a temperature which is sufficient to permit the reaction of the metal halide with the refractory metal to form the volatile halide, which escapes and to form the metal coating, bounded by diffusion of the brazing metal to the surface of the refractory metal.
