SHERARDIZING METHOD

摘要

The invention relates to a method for coating a surface of at least one substrate with zinc, wherein the at least one substrate to be coated is heat-treated together with zinc as the coating agent at a temperature between 200 and 500°C, the oxygen content of the atmosphere contained in the reaction chamber in which the substrate is heat-treated being adjusted prior to the heat treatment in the reaction chamber to less than or equal to 5% by volume. The heat treatment is then started in the reaction chamber in the atmosphere so produced and the heat treatment is carried out in the reaction chamber, no gas being supplied or no oxygen-containing gas being supplied or gas being supplied to the reaction chamber during heat treatment, the gas being supplied having been pretreated to have an oxygen content of not more than 100 ppm.
