Comparative example
Comparative example 1: comparative example 1 is different from example 1 in that only the step S5 originally existing in example 1 was omitted in comparative example 1, so that the step of "immersing the dried product in RA-series anti-fingerprint coating solution, taking out the product after the coating was uniform, and baking at 150 ℃ for 40 minutes" was omitted, and the remaining steps were exactly the same as in example 1 in comparative example 1.
The anti-fingerprint property and the abrasion resistance of examples 1 to 5 and comparative example 1 were measured, and the test results are shown in Table 1:
TABLE 1
The color properties of examples 1-5 were tested and the test results are shown in Table 2:
TABLE 2
The test results in table 2 show that the titanium and titanium alloy anodic oxidation multicolor pattern coloring process provided by the invention innovatively uses the improved electroplating brush pen application, so that any combination of more complex patterns with any colors and more pattern combinations are displayed on the surface of the titanium alloy, and artificial artistic signature and pattern drawing can be realized by the improved electroplating brush pen.
