  Vapor galvanizing \Va"por gal"va*niz`ing\ (Metal.)
     A process for coating metal (usually iron or steel) surfaces
     with zinc by exposing them to the vapor of zinc instead of,
     as in ordinary galvanizing, to molten zinc; -- called also
     {Sherardizing}. Vapor galvanizing is accomplished by heating
     the articles to be galvanized together with zinc dust in an


     air tight receptacle to a temperature of about 600[deg] F.,
     which is 188[deg] below the melting point of zinc, or by
     exposing the articles to vapor from molten zinc in a separate
     receptacle, using hydrogen or other reducing gas to prevent
     oxidation.
     [Webster 1913 Suppl.]
