摘要： A method for diffusion coating a surface of a metal substrate with zinc comprises the steps of: a1) applying a suspension, comprising a liquid and zinc and/or a zinc alloy as a diffusion source or zinc donor, onto the surface of the substrate to be coated, or a2) applying a liquid onto the surface of the substrate to be coated and subsequently applying zinc and/or a zinc alloy as a diffusion source or zinc donor onto the liquid; and b) drying the substrate obtained in step a1) or a2); c) carrying out a heat treatment of the substrate obtained in step b) at a temperature between 200 and 500° C., but below the melting temperature of the diffusion source in a shielding gas atmosphere; and d) removing the mixture applied in step a1) or a2).

摘要： In a method for the coating of a surface of at least one substrate with zinc in which 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., wherein, before the start of the heat treatment in the reaction space in which the substrate to be coated is heat treated, the oxygen content in the atmosphere contained in the reaction space is set to less than/equal to 5 volume percent and the heat treatment is then started in the atmosphere obtained in this manner in the reaction space and the heat treatment is carried out in the reaction space, with no gas being supplied into the reaction space during the heat treatment or with no gas containing oxygen being supplied or with gas being supplied which has been pretreated so that it has an oxygen content of a maximum of 100 ppm.
摘要翻译：在用锌涂覆至少一种基材的表面的方法中，其中待涂覆的至少一种基材与锌一起作为涂层剂在200-500℃的温度下进行热处理，其中，在将要涂覆的基底的反应空间中的热处理开始进行热处理，将反应空间中所含的气氛中的氧含量设定为小于等于5体积％，然后开始热处理在反应空间中以这种方式获得的气氛中，并且在反应空间中进行热处理，在热处理期间没有气体供应到反应空间中，或者在没有供应含氧气体或供应气体的情况下，已经进行了预处理，使得氧含量最高达100ppm。
