摘要： A method for making a lamination insulated by iron-manganese phosphate comprises the following operations:1. The lamination is treated with an acid or basic medium to eliminate the surface layer of the lamination that contains excess silicon and aluminum.2. The lamination is rinsed.3. The lamination is brought into contact with a solution of phosphoric acid containing iron phosphate and manganese phosphate for sufficient time to obtain an insulative layer of the required thickness.

摘要： A method of enhancing the corrosion resistance of sintered stainless steel, particularly against attack by acids, such as acetic acid, under non-oxidizing conditions. The sintered stainless steel is activated, for example by treatment with acid and is then treated with a phosphate containing solution. The sintered stainless steel has improved resistance to subsequent attack by acid.

摘要： A process of providing an inorganic anti-stick coating directly on non-oriented, semi-processed electrical steels by applying to such steels a coating solution containing Al.sup.+++, Mg.sup.++, and H.sub.2 PO.sub.4.sup.- in a specified relative relationship, the concentration of Al.sup.+++, Mg.sup.++, and H.sub.2 PO.sub.4.sup.- comprising 100 parts by weight calculated as Al.sub.2 O.sub.3, MgO and H.sub.3 PO.sub.4, respectively, on a water-free basis. The coating solution may additionally contain from 0 to 150 parts by weight of colloidal silica on a water-free basis. Chromic anhydride (C.sub.r O.sub.3) may be added to the coating solution to improve its wettability and improve the moisture resistance of the anti-stick coating. The coating solution is so diluted with water as to provide a uniform coating as thin as possible to prevent lamination sticking and having a coating weight of less than 2 grams per square meter on each side. The coated electrical steel is subjected to a heat treatment to cure the anti-stick coating thereon.

摘要： A method of treating oxidized surfaces but especially metal surfaces using a mixture by which deep entry of porous rust can be achieved and reduction of the oxidation effected deep within the porous structure with substantial capacity to effect total conversion and especially with preferred chemicals, replacement with an insoluble protective coating can be effected. The process limits the need for physical removal of rust and the treatment of rust provides a different mechanism by which subsequent rusting can be reduced in the case of iron and steel and other metals.
