    摘要： An acidic, aqueous composition contains a trivalent chromium compound, an organo-functional silane, and a compound of a group IV-B element. The composition protects metal surfaces, preferably aluminum and aluminum alloys, against corrosion and improves their paint adhesion. The trivalent chromium compound may comprise chromium fluoride and optionally others, such as chromium nitrate. The organo-functional silane is preferably an aminopropyltriethoxy silane, and the compound of a group IV-B element is preferably fluorozirconic acid. The composition can either be dried-in-place or rinsed before a further coating layer is applied. The composition may also include at least one polymer having a plurality of both carboxylic functional groups, alone or with hydroxyl groups. A process uses the aqueous composition either with or without the organo-functional silane along with a sealing step following the application of the aqueous composition; the sealing step involves applying a sealing composition, including an organo-functional silane, to the metal surface.

    摘要： A process of cleaning very sparingly water soluble soaps off workpieces after cold forming them is made considerably more economical by using a cleaning solution that causes the removed soap anions to form a separate floating solid phase that can easily be skimmed from the surface of the cleaning solution. When such a separation is made, much longer intervals between replacement of the cleaning solution are possible while still obtaining satisfactory results. A preferred cleaning solution for such a process comprises hydroxides, neutral salts, polymeric quaternary ammonium cations, and a sequestering agent for the counterions of the soap anions to be cleaned.

    摘要： Problems of extensive foaming and/or of sticky deposits on process equipment that often arise when metal soaps from metal articles that have been given a metal soap containing surface to aid in drawing are removed with aqueous alkaline clearners can be avoided by including in the cleaners used anions such as calcium and magnesium that are capable of precipitating the anions of the metal soaps. The cleaners advantageously also contain chelants, a mixture of nonionic and anionic surfactants, and phosphorus containing anions. Anions from the metal soaps are eventually precipitated from the cleaners used as non-sticky sludge that can be easily separated from the cleaners.
