摘要： A nickel and/or cobalt deposition process which can be run at a nearly neutral pH and which rapidly deposits nickel and/or cobalt in quantities large enough to improve the paint adhesion and post coating corrosion resistance and which has a good solution stability, is achieved by treating zinc coated sheet steel with an aqueous solution that has a pH between 5 and 10 inclusive and comprises (A) a total of at least 0.01 g/L of metal ions selected from the group consisting of NI and Co ions and (B) a sufficient amount to fully complex the metal ions recited in part (A) of complexing agents selected from the group consisting of ammonia and organic compounds having at least one amino group in the neutral region. The substitution precipitation reaction of nickel and cobalt is substantially accelerated by the presence, as a third component in addition to the metal ion and complexing agent, of at least one ionic species or compound selected from the nitrite ion, nitrate ion, thiocyanate ion, thiosulfate ion, thiourea, phosphite ion, hypophosphite ion, and perchlorate ion.

摘要： A phosphate surface-treatment bath which contains a cationic organic polymeric compound (or salt thereof) that contains at least one cationic nitrogen atom and has a molecular weight of 1,000 to 1,000,000 forms a highly corrosion resistant film on metal surfaces (e.g., iron, zinc, aluminum, etc.) that is also an excellent paint undercoat. The film preferably is one in which the resin composed of the cationic organic compound (or salt thereof) has penetrated into the grain boundaries between phosphate crystals with an accompanying formation of a phosphate crystal/resin composite. A film formed in accordance with the present invention affords a remarkable improvement in corrosion resistance and paint adherence, compared with the phosphate conversion achieved with the same treatment, except for the omission of the organic polymer containing cationic nitrogen. In addition, even when the primer coating step is omitted, the present invention exhibits a performance approximately equivalent to the application of a primer coating on a conventional phosphate film.
摘要翻译：包含含有至少一个阳离子氮原子并具有1,000至1,000,000分子量的阳离子有机聚合物（或其盐）的磷酸盐表面处理浴在金属表面（例如铁，锌）上形成高度耐腐蚀的膜，铝等），其也是优异的漆底漆。该膜优选其中由阳离子有机化合物（或其盐）组成的树脂渗透到磷酸盐晶体之间的晶界中并伴随形成磷酸盐晶体/树脂复合物。与通过相同处理实现的磷酸盐转化率相比，根据本发明形成的膜除了含有阳离子氮的有机聚合物以外，提供了耐腐蚀性和涂料粘附性的显着改进。此外，即使省略底漆涂布步骤，本发明也显示出与常规磷酸盐膜上底漆涂层的应用大致相同的性能。
