Corrosion-resistant coating of steel product, e.g. sheet for use in automobile bodywork, by applying two metal layers, with intermediate oxide removing chemical preconditioning to improve interlayer adhesion
Corrosion-resistant coating of steel product, e.g. sheet for use in automobile bodywork, by applying two metal layers, with intermediate oxide removing chemical preconditioning to improve interlayer adhesion
In a method for coating steel products by successively applying first and second metallic layers, the first layer is treated with a chemical preconditioning agent (I) to remove oxide before applying the second layer.
