Abstract

PURPOSE:To produce a stainless steel sheet having a patina-like surface, superior decorativeness and corrosion resistance by coating a stainless steel substrate with a film of a green copper compd. CONSTITUTION:A stainless steel substrate is coated with a film of a green copper compd. such as basic copper carbonate, copper oxide, copper hydroxide or copper sulfate by sputtering, ion plating or other method. The film has patina-like appearance, superior strength and adhesion. The copper compd. coated stainless steel sheet is similar in decorativeness to a copper sheet having formed patina and has superior corrosion resistance, so the steel sheet can be used as an external material such as a roofing material.

Prior Art The greenish rust that forms on metallic copper under certain conditions is a mixture of basic copper carbonate, copper hydroxide, copper oxide, copper sulfate, etc. and is collectively called verdigris. Patina is a chemically stable and dense substance, so when it exists on the surface, it gives materials corrosion resistance.It is also a substance that exhibits a characteristic green color, so it has been used as roofing and wall materials since ancient times. Copper plates with a naturally occurring patina on their surfaces have been used for such purposes.

In addition to the use of copper plates that wait for patina to develop naturally, in recent years copper plates that have been actively patinaed in advance have come to be used as exterior materials. One way to proactively create such a copper plate with a patina is to apply a chemical such as a salt solution to a copper plate whose surface has been cleaned, and then expose it to the atmosphere to allow a chemical reaction that causes rust to occur on the surface of the copper plate. The conventional technique was to generate a verdigris-like substance and then leave it until the surface became stable.
