- the surface of the molded substrate is treated with zinc phosphate and manganese phosphate to facilitate cold working such as wire drawing, coiling, and wire forming.
- Zinc phosphate and manganese phosphate contain water of crystallization, so when the anti-corrosion film is baked at a high temperature of 230 ° C or higher, it becomes an anhydrous salt, and the film changes in quality and decreases the adhesion to the substrate. Let For this reason, in the present invention, a strong alkaline degreasing solution is used to substantially remove the fats and oils.

- the first film consisting of an inorganic compound-containing film that does not contain chromium exhibits an excellent anti-bacterial effect when baked and coated at a higher temperature than before, so zinc phosphate is manganese phosphate when baking at this high temperature. Releases crystal water and alters the first coating. For this reason, the adhesion between the first film and the substrate is lowered. Therefore, in the present embodiment, the first film is formed on the surface of the base material in which the residual ratio of the lubricating film is less than 25% of the surface area of the base material.

Since the lubricating coating has high adhesion to the substrate, it is degreased by immersing it in a strong alkaline solution with a pH of 10 to 13. If the pH of the degreasing solution is less than 10, the lubricating film on the surface of the substrate cannot be effectively removed. On the other hand, if the pH exceeds 13, it may be necessary to take measures against corrosion in the degreasing tank. Therefore, it is not preferable. A more preferable pH value is 11 to 13.
- This strong alkaline solution is an aqueous solution containing 0.1 to 20% by mass of sodium hydroxide and an accelerator mainly composed of sodium metasilicate for promoting detergency. If the main component sodium hydroxide is less than 0.1% by mass, the zinc phosphate coating or the manganese phosphate coating cannot be sufficiently removed. Further, if it is contained in a large amount exceeding 20% by mass, it may cause inconveniences such as dissolution and precipitation of the iron base, which is not preferable. A more preferable content of sodium hydroxide is 1 to 18% by mass.

- the coating film residual ratio is a percentage of the area of the phosphoric acid coating film occupying the visual field area when the substrate surface after the degreasing treatment is observed with a microscope (50 times). Since Sample 0 has not been degreased, the film remaining rate is 100%. Sample 1 is a standard sample with a film remaining rate of 25%. In other words, it has been confirmed that good adhesion of the first film can be obtained if the remaining film ratio is 25% or less. Therefore, it is presumed that Samples 2 to 10 shown in Table 1 have good adhesion of the first film.

- the hanger method dip drain method
- other methods such as spray coating are used. be able to.
- the baking temperature of the first film should be in the range of 250-400 ° C. If the baking temperature is less than 250 ° C, sufficient sacrificial protective action such as zinc powder cannot be obtained, and sufficient film hardness and adhesion cannot be obtained. On the other hand, if the temperature exceeds 400 ° C, the zinc powder may be altered, which is not preferable. More preferably, it is 300-370 degreeC.
- the coating amount of the first film is preferably 150 to 50 OmgZdm 2 . The coating amount is not sufficient corrosion resistance can be obtained with less than 15 OmgZdm 2, also, not suitable because exceeding 50 OmgZdm 2 the adhesion to the substrate is likely to peel off and drop. More preferably, it is 2 ° 0 to 40 OmgZdm 2 .
- the first film containing zinc has the electrochemical sacrificial protective action of zinc and the blocking action (paria effect) that blocks the substrate surface from the atmosphere by the laminated metal flakes. Therefore, it is possible to effectively protect the metal parts formed from steel. wear.
- the first coating containing zinc has an electrochemical sacrificial protective effect of zinc and a shielding effect from the atmosphere by secondary zinc products, so it is effective for metal parts formed of steel. Can be protected. However, in order to prevent the appearance of the first film and the occurrence of white glaze due to the oxidation of zinc, it is desirable to further form a second film that protects the first film.
