Patent number: 7147934Abstract: A chemically processed steel sheet comprises a steel base coated with an Al—Si alloy plating layer, whose Si content is preferably adjusted to 5–13 mass % as a whole and to 7–80 mass % at a surface, and a converted layer generated on the surface of the plating layer. The converted layer contains both soluble and scarcely-soluble compounds. The soluble compound, such as a manganese oxide or hydroxide, or a valve metal fluoride, is once dissolved into water in an atmosphere and then re-precipitated as scarcely-soluble compounds at defective parts of the converted layer. The scarcely-soluble compounds act as a barrier for corrosion prevention of a base steel. Due to the re-precipitation, i.e., self-repairing faculty, excellent corrosion resistance of the converted layer is still maintained even after defects are introduced therein during plastic deformation of the steel sheet.Type: GrantFiled: April 22, 2004Date of Patent: December 12, 2006Assignee: Nisshin Steel Co., Ltd.Inventors: Masaya Yamamoto, Mitsuo Asabuki, Shigeyasu Morikawa, Shinya Furukawa, Hirofumi Taketsu
