摘要： The invention concerns a method of phosphating metal surfaces consisting at least partially of iron or steel using low-zinc technology, in which the metal surfaces are brought into contact with aqueous acidic phosphating solutions at between 30 and 65 DEG C for between 1 and 8 minutes. The phosphating solutions contain: between 0.4 and 2.0 g/l Zn; between 7 and 25 g/l P2O5; between 0.005 and 0.5 g/l peroxide (calculated as H2O2); and between 0.01 and 10 g/l formiate (calculated as formiate ion). The phosphating solutions are free from chlorate and added nitrite, the weight ratio of free P2O5 to total P2O5 therein is set at a value of between 0.03 and 0.20, and the amount of free acid is set at a value of between 0.5 and 2.5. Additionally, the phosphating solutions can contain up to 30 g/l nitrate and manganese, magnesium, calcium, lithium, tungstate, vanadate, molybdate or combinations thereof, optionally also nickel and/or cobalt each in amounts of up to 3 g/l, and optionally also up to 0.030 g/l copper. The weight ratios of Mn : Zn, Mg : Zn, Ca : Zn and optionally of Ni and/or Co : Zn should be at most 2 : 1 in each case. The method is suitable in particular for preparing metal surfaces for subsequent electrophoretic enamelling, in particular cathodic electrophoretic enamelling.

摘要： An improved lubricating layer for heavy cold working of iron and steel objects can be obtained by first phosphating them with a solution comprising, in percentages by weight, 0.3 to 2.5 % of zinc ions, 0.01 to 2.0 % of ferrous ions, 0.5 to 5.0 % of phosphate ions, 0.7 to 12.0 % of nitrate ions, and 0.02 to 0.25 % of water soluble aromatic organic compounds that contain both nitro and sulfonic groups, with the ferrous ion and zinc ion contents additionally being such that the weight ratio of ferrous ions to zinc ions in the phosphating solution in within the range from 0.005 to 3.0. Optionally, the phosphating solution may also contain from 0.2 to 2.0 % of calcium ions, and when it does, the weight ration of calcium ions to zinc ions in the solution should also be in the range from 0.7 to 4.0. After phosphating, the phosphated surfaces are treated with a conventional lubricant, preferably a weakly alkaline solution of sodium stearate.

摘要： Disclosed is a treatment solution for use in the formation of a black trivalent chromium chemical conversion coating film with uniformly stabilized black wash, luster and corrosive resistance irrespective of the type of the acidic, neutral or alkaline zinc plating bath employed or the presence or absence of nickel eutectoid. Also disclosed is a method of forming the black trivalent chromium chemical conversion coating film. The treatment solution comprises a trivalent chromium ion, a chelating agent capable of forming a water-soluble complex with the trivalent chromium, at least one metal ion selected from the group consisting of a cobalt ion, a nickel ion and an iron ion, and formic acid or a salt thereof as a buffer for hydrogen ion concentration. The treatment solution can be used for forming a black hexavalent chromium-free chemical conversion coating film on zinc or a zinc alloy.
