    摘要: The invention relates to a method for treating metallic surfaces consisting of zinc, magnesium or aluminium or of the alloys of zinc, magnesium or aluminium, to which lacquer, coatings of plastic material, paint, sealants or adhesives are applied after treatment. The treatment of the metallic surfaces takes place at between 10° C. and 100° C. by immersion, spraying or rolling with an aqueous solution. The solution has a pH of between 2 and 13 and contains one or more compounds of the type XYZ at a concentration of between 10−5 and 1 mol/l. Y is an organic group containing between 2 and 50 C atoms and has a straight-chain structure. X is a COOH, HSO3, HSO4, (OH)2PO, (OH)2PO2, (OH)(OR′)PO or (OH)(OR′)PO2 group. Z is a OH, SH, NH2, NHR′, CN, CH═CH2, OCN, epoxy, CH2═CR″—COO, acrylamide, COOH, (OH)2PO, (OH)2PO2, (OH)(OR′)PO or (OH)(OR′)PO2 group. R′ is an alkyl group with between 1 and 4 C atoms. R″ is an H atom or an alkyl group with between 1 and 4 C atoms. Groups X. and Z are each bonded to group Y in their final positions.

    摘要: Sequentially applying two different coatings, in two steps, to metallic surfaces. Metallic surfaces are contacted at temperatures from 10-100° C. with aqueous solution A and then with aqueous solution B, or vice versa, wherein solution A contains an effective amount of zirconium, hafnium, titanium, silicon and/or boron, and of fluoride as ions and/or complex ions able to pickle metallic surfaces and generate a coating on the pickled metallic surface and that solution B contains an effective amount of one or more of XYZ, X*Y*Z* and/or X*Y*Z*Y*X* where Y is an organic group with 2-50 carbons, where X as well as Z is a group—each same or different—of OH—, SH—, NH2—, NHR—, CN—, CH═CH2—, OCN—, CONHOH—, COOR′, acrylamide-, epoxide-, CH2═CR″—COO—, COOH—, HSO3—, HSO4—, (OH)2PO—, (OH)2PO2—, (OH)(OR′)PO—, (OH)(OR′)PO2—, SiH3—, Si(OH)3—, where R′ is an alkyl group with 1-4 carbons, where R″ is hydrogen or an alkyl group with 1-4 carbons, and where X and Z are each bound to the Y in their terminal position, where Y* is an organic group with 1-30 carbons, where X* as well as Z* is a group—each same or different—of OH—, SH—, NH2—, NHR′—, CN—, CH═CH2—, OCN—, CONHOH—, COOR′, acrylamide-, epoxide-, CH2═CR″—COO—, COOH—, HSO3—, HSO4—, (OH)2PO—, (OH)2PO2—, (OH)(OR′)PO—, (OH)(OR′)PO2—, SiH3—, Si(OH)3—,N—CH2—PO(OH)2—, —N—[CH2—PO(OH)2]2— where R′ is an alkyl group with 1-4 carbons, where R″is hydrogen or an alkyl group with 1-4 carbons.
