Summary of the invention
Conventionally, as be coated with coating to make the coloring of aluminum formed body surface, so
Along with the lasting use of aluminum formed body, its white film peeling etc. sometimes thus damage attractive in appearance.
It addition, according to by electrophoresis method of filler pigment in the pore of anode oxide film, in order to fill out
Fill the amount that this pigment can play the degree of tinting strength, tinting power, it is necessary to make the diameter of this pore become big.Since so,
Likely produce harsh feeling on the surface of aluminum formed body consequently, it is possible to damage attractive in appearance.
And then, due to the coloring film obtained by so un-densified film, and being relatively large in diameter of pore,
So before filling titanium oxide, the reflection of the light that reason pore causes, aluminum formed body has had certain
The light interference of the degree of kind, thus present the white with the transparency.Therefore, it is impossible to obtain opaque
White films.
It addition, when carrying out stable heavy colour coloring by electrophoresis, owing to cell current during electrophoresis is less,
So there is the pigment trend that not surface excess outside pore separates out in pore.
It addition, as above-mentioned patent documentation 1 is recorded, according to having at anode oxide film
Make titanium dioxide separate out on surface and hole inner face thus form science and engineering at the titanyl electrolysis of titanium dioxide film
Sequence and the method for operation burnt till by this titanium dioxide film, make the photocatalyst titanium dioxide of q.s
Separate out more difficulty, simultaneously because the aluminum formed body that thermostability is relatively poor is carried out high-temperature heating, therefore
And there is the deformation of its formed body or the probability of physical property change.

Oxidation processes film etching so that barrier layer dissolve operation, so this etching work procedure cannot only make certainly
Barrier layer in pore dissolves, and makes anodized film entirety etch.Its result, relative to sun
Pole oxidation processes film is integrally formed convex-concave surface, even if pigmentable, is also only to define as aluminium sheet and deposits
On concavo-convex uneven surface.
Further, since the anodized film being temporarily forming is etched, thus this anodic oxidation
Process film disappears.Therefore, even if pore exists, also become in pore and cannot be anodized film
The state of protection, along with the use of aluminium, pore is interior, aluminium material surface corrosion.
