    Abstract: In the practice of the instant invention, a lubricating phosphate coating is applied to the surface of a ferrous-base metal article by contacting the surface with an aqueous acidic phosphate coating solution which contains an amount of hydroxylamine which is effective in increasing the rate at which the phosphate coating deposits from the solution. The resulting coated article is then subjected to cold deformation.In a preferred embodiment, the metal article is additionally contacted with a second lubricating compound after the phosphate coating is applied. In addition to phosphate the coating solutions employed preferably contain one or more of the following ions: zinc, manganese, nitrate, nickel, ferrous, ferric, copper, fluoride, or mixtures thereof.

    Abstract translation: 在本发明的实践中，通过使表面与含有一定量的羟胺的酸性磷酸盐水溶液的水溶液接触，将铁酸盐金属制品的表面施加润滑磷酸盐涂层，所述羟胺含量有效提高速率 磷酸盐涂层从溶液中沉积。 然后将所得涂层制品进行冷变形。 在优选的实施方案中，在施加磷酸盐涂层之后，金属制品另外与第二润滑化合物接触。 除了磷酸盐以外，所用的涂层溶液优选含有一种或多种以下离子：锌，锰，硝酸盐，镍，亚铁，三价铁，铜，氟化物或其混合物。
