摘要： In a method for coating steel strips having a base material composition (in weight-%) of: C 0.04-1.0; Mn 9.0-30.0; Al 0.05-15.0; Si 0.05-6.0; Cr≦6.5; Cu≦4; Ti+Zr≦0.7; Nb+V≦0.5, remainder iron including unavoidable steel-incidental elements, the steel strip undergoes annealing and subsequently is coated electrolytically with a coat formed from zinc or a zinc-containing alloy. During the course of annealing of the steel strip at temperatures between 800 and 1000° C. under a N2-H2 containing atmosphere, a surface-near zone is formed which is enriched with nitrides through reaction with elements contained in the steel, thereby preventing molten zinc from penetrating into the base material during welding of the coated steel strip.
