Because the hardness of the oxide film layer is higher, the formability is poorer, and the oxide film is easy to crack after bending and forming, the etching and anodic oxidation process can only be used for treating formed parts generally and only used for exterior trimming parts such as welcome pedals, ceiling supports and the like with lower appearance requirements.
In addition, after oxidation coloring, surface sealing treatment is required, and the oxidation colored layer after sealing is mostly not suitable for spraying treatment of a surface coating due to the problems of adhesion and the like, which also becomes a bottleneck for limiting the expansion and application of the etching anodic oxidation coloring process in a wider field.
