ABSTRACT:
This invention relates to an improved process for application of a metal-comprising coating to a metal-comprising surface without using a flux. The metal-comprising surface must be wettable by or become wettable upon contact with a bath of the metal-comprising coating. Application of the coating is carried out in an environment which is inert at least with respect to the coating material during the time period of its application to the metal-comprising surface, and preferably inert with respect to both the coating material and the metal-comprising surface. The inert environment temperature is sufficiently low that no damage is done to the metal-comprising surface and no damage is done to other materials adjacent to the metal-comprising surface.
