Embodiment
[0127] Next, the surface treatment material of the present invention was produced as a trial and its performance was evaluated, which will be described below.
[0128] (Invention Examples 1 to 21)
[0129] On the aluminum base material (0.2mm×30mm×30mm in size) shown in Table 12, the electrolytic degreasing process was carried out according to the above conditions. The indicated zinc replacement treatment conditions were followed by zincate treatment constituting the above-mentioned second surface activation treatment, and partial dissolution was performed after forming a zinc-containing thick film layer with the thickness shown in Table 12, thereby forming a zinc-containing thick film layer with the thickness shown in Table 12. layer. For Inventive Examples 5, 12 to 14 and 21, the second surface activation treatment was not performed (the zinc-containing layer was not formed.). Next, for Invention Examples 1 to 21 (except Invention Example 14.), use an acid solution contain...
example 1~4
[0133] For Conventional Examples 1 to 4, the electrolytic degreasing process was carried out under the above conditions on the aluminum substrate (dimensions 0.2mm×30mm×30mm) shown in Table 13, and then, for Conventional Examples 1 and 2, by performing the conventional Zinc replacement treatment (zincate treatment) to form a zinc-containing layer with the thickness shown in Table 12. In addition, in Conventional Example 3, the conventional zinc replacement treatment (zincate treatment) was not performed, and in Conventional Example 4, immersion treatment was performed in a nickel plating solution containing hydrofluoric acid and a nickel salt shown in Table 13. Thereafter, in Conventional Examples 1 to 4, the first surface activation treatment was not performed, and the above-mentioned surface treatment film formation step was performed to form a surface treatment film consisting of two metal layers with the thicknesses shown in Table 12. , and make surface treatment materials...
