摘要： A selective absorber of solar energy employing an aluminum alloy sheet as a substrate on which a chemical conversion coating is initially formed. The coating is thereafter heat-treated into an oxidized, dark-colored coating of selective solar absorption nature. Also disclosed is a process for producing the absorber. The process comprises a chemical conversion treatment step for formation of the initial coating, and a high-temperature oxidation treatment step for final formation of the selective coating. The latter step includes preventing atmosphere in the vicinity of the substrate surface from circulating.

摘要： Aqueous acidic coating solutions are described for treating zinc or zinc alloy surfaces comprising trivalent chromium as substantially the only chromium ion present, fluoride ion, an acid other than nitric acid, and an oxidizing agent. The coating solutions containing trivalent chromium as substantially the only chromium ion present preferably are prepared by reducing an aqueous solution of hexavalent chromium with sufficient reducing agent to reduce all of the hexavalent chromium to trivalent chromium. Chromate coatings on zinc and zinc alloy surfaces are produced by contacting said surfaces with an aqueous acidic solution of the invention.

摘要： A chromium-containing coating composition, also containing pulverulent metal, will provide a coating of excellent corrosion resistance when the composition contains urea as at least a part of the reducing agent, and when the composition also contains particular pH adjusting agent. The reducing agent of the composition is used in regard to the hexavalent chromium contained in the chromium portion of the composition. The pH adjusting agent should be a compound of zinc. In addition to achieving excellent corrosion resistance, resulting coatings can provide the other desirable characteristics for coated substrates, such as topcoat adhesion and formability, without deleterious effect.

摘要： Metal treating compositions, containing chromic acid and pulverulent zinc, and which find particular utility in the coating of metal substrates prior to painting, now exhibit extended bath stability through pH adjustment. The key to the adjustment is not in the final bath makeup. Rather, the adjustment is made during preparation of a precursor component containing chromic acid. Such component of adjusted pH may then be blended with additional composition ingredients including the pulverulent zinc to form a bath of excellent stability, e.g., extended freedom from gelation.
摘要翻译： 含有铬酸和粉状锌的金属处理组合物在涂漆前在金属基材的涂覆中具有特别的用途，现在通过pH调节显示出延长的浴稳定性。 调整的关键不在于最后的洗浴妆容。 相反，在制备含有铬酸的前体成分时进行调整。 然后可以将调节pH的这种组分与另外的组合物组分（包括粉状锌）混合以形成优异稳定性的浴，例如延长的凝胶化自由度。
