    摘要： Enhanced resistance to the corrosion of metals such as aluminum, zinc, magnesium and the like is achieved by the application of a metallo-gel film. The composition of the coating uniquely includes liquid manganese nitrate and sodium tungstate as accelerators which accelerate and activate the chromate sources to coat the metal surface being treated.

    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： This invention relates to the use of sodium nitroferricyanide as a substitute for sodium or potassium ferricyanide in nitric acid acidified, hexavalent chromium-fluoride solutions for the treatment of aluminum and its alloys (wherein aluminum is the principal constituent), providing coatings having excellent corrosion-resistance, reduced surface powdering, and improved adhesion and appearance. Small amounts of sodium vanadate may also be added to effectively modify the characteristics of the deposited coatings. Controlled build-up of the protective coatings, produced by chemical reaction between the active components of the solution and the aluminum or aluminum alloy surfaces, are readily accomplished within a temperature range of 65.degree.-85.degree. F. and an immersion time of 5-10 minutes.
