MATERIAL DE ACO REVESTIDO,DOTADO DE EXCELENTE RESISTENCIA A CORROSAO,E APARELHO PARA REVESTIR UM MATERIAL DE ACO COM MANGANES HIDRATADO COMPACTO,FORMADO SOBRE O REVESTIMENTO DE MANGANES

摘要

Manganese coated steel materials having a compact film of hydrated manganese oxide formed on the manganese coating by heating and drying. Manganese coated steel materials of the present invention show very excellent corrosion resistance in ordinary corrosive environments as well as special corrosive environments such as marine environments and young plant cultivation in mountaineous forests. For further improvement of corrosion resistance, organic coating and metal coatings are applied.
