  • Method for filling small holes or covering small recesses in the surface of substrates
    Patent number: 5705230
    Abstract: The improved method comprises contacting a substrate 5 at least once by a liquid containing the elements that compose a pure metal or an alloy with which the small holes or recesses 3a in the substrate 5 are to be filled or covered, whereby the liquid wets the inner surfaces of said small holes or recesses 3a while, at the same time, said pure metal or said alloy is deposited on the surface of said substrate 5. The method is capable of filling small holes or covering small recesses in the surface of the substrate 5 with improved efficiency while, at the same time, it improves the heat resistance and materials stability of the part that contains the formed filling or covering layer.
