Metal surface treatment method |
| abstract |
PROBLEM TO BE SOLVED: To form a zinc phosphate film suitable for cationic electrodeposition coating of a metal, particularly a metal molded product having both a ferrous metal surface and a zinc metal surface at the same time, and suitable for a closed system. To provide a simple metal surface treatment method. SOLUTION: This method is a metal surface treatment method including a step of subjecting an object to a chemical conversion treatment by immersion using an aqueous solution of acidic zinc phosphate, wherein the method does not substantially contain calcium ions as a promoter and zinc nitrite [ A metal surface characterized by using an aqueous zinc nitrite solution containing 0 to 6500 ppm of sodium ions and 0 to 20 ppm of sulfate ions when converting the concentration of Zn (NO 2 ) 2 ] aqueous solution to 10% by weight as NO 2. Processing method. |
