    摘要： A steel sheet mainly suitable for strength members of automobiles or building materials, which has a tensile strength of 1,180 MPa or more, and which is excellent in delayed fracture resistance and primary rust prevention performance. The steel sheet includes a coating, placed on a surface of a cold-rolled steel sheet with a tensile strength of 1,180 MPa or more, containing one or more metalates selected from molybdates and tungstates and a P compound. The sum of the coating weights of the metalates in terms of Mo and W is 10 mg/m2 to 1,000 mg/m2 and is preferably 50 mg/m2 to 1,000 mg/m2. The coating weight of the P compound in terms of P is 10 mg/m2 to 1,000 mg/m2.

    摘要： A metallic sliding material including at least a support member with a sliding surface and an inorganic compound coating layer formed on the sliding surface is disclosed. The sliding surface is formed from an aluminum alloy or a reinforcing material-containing aluminum alloy. The inorganic compound coating layer is formed from at least one aluminum compound, and at least one phosphorus compound, and at least one member selected from the group of molybdenum compounds, tungsten compounds, and chromium compounds. These compounds are present in such concentrations that molybdenum, tungsten, and chromium collectively constitute 2 to 48% by weight of the inorganic compound coating layer, aluminum constitutes 1 to 25% by weight of the inorganic compound coating layer, phosphorus constitutes 1 to 25% by weight of the inorganic compound coating layer, and the balance of the inorganic compound coating layer is oxygen and impurities.

    摘要： A method and a treatment solution for posttreatment of an article with a metallic surface, where the metallic surface is made of one or more metals of a standard oxidation potential within the range -2.5 to +0.5 V. A thin coating is formed on the metallic surface by a treatment with an aqueous solution containing a molybdenum compound selected among molybdic acid and salts thereof in a concentration of 2.9 to 9.8 g/l calculated as molybdenum, as well as a compound capable of forming a heteropolymolydate, such as phosphoric acid, together with a molybdate. The treatment is performed under conditions where the metal surface is maintained at a potential within the range of -600 and -1800 mV/nhe. A corrosion-protecting and/or decorative effect is obtained which can be compared with the effect obtained by conventional chromate treatment, and which avoids the environmental and toxicologic drawbacks associated with the chromate treatment.
