Abstract
A method for plating a stainless steel substrate is provided. According to one embodiment, the method comprises sandblasting at least one joint surface of a stainless steel substrate and treating the joint surface of the stainless steel substrate with an aqueous solution (acid bath) which contains sulfuric acid, nitric acid and hydrofluoric acid. The stainless steel substrate is then rinsed with hydrochloric acid. The method further includes galvanic deposition of a nickel plating on the joining surface of the stainless steel substrate and the subsequent deposition of a tin layer on the nickel-coated joining surface of the stainless steel substrate.
