In the aqueous solution contact process of thing, the aqueous solution has trickle corrosiveness to the surface 12 of metal one, can be connect in metalwork 10
The surface 12 for touching the aqueous solution forms multiple nano-pores 122.In another embodiment, can also be by laser laser carving in metal
One surface 12 of part 10 forms nano-pore 122.The process principle of laser laser carving is one that metalwork 10 is acted on by laser beam
Surface 12, the material for making to be formed the opening position of nano-pore 122 absorbs laser energy and vaporization, so as to form nano-pore
122, it is not necessary to carried out by the contact with material.Specifically, metalwork 10 can be aluminium alloy, or almag, or
Other alloy materials of person.
S102：Decorative layer 20 is formed on a surface 12 of metalwork 10.
Referring to Fig. 3, formed in metalwork 10 on the surface of nano-pore 122 and formed a decorative layer 20.Specific decoration
Layer 20 is enamelled coating, optical thin film or decorating film etc..Due to being thick with multiple nano-pores 122 on a surface 12 of metalwork 10,
Therefore at least a portion 22 of decorative layer 20 can be penetrated into nano-pore 122, so as to snap tight against in nano-pore 122, Jin Er great
Adhesion between big enhancing decorative layer 20 and metalwork 10.Avoid the occurrence of paint, or decorating film/optical thin film partial exfoliation
Phenomenon.
Alternatively, decorative layer 20 can be formed on a surface 12 of metalwork 10 by Shooting Technique through being projected in film.Using
The mode projected in film, material is formed has an impulse force when 10 1 surface 12 of metalwork, it is easier into nano-pore 122
In.
During other are implemented, alternatively, enamelled coating can be also formed on a surface 12 of metalwork 10 by the way of spraying.
During other are implemented, alternatively, decorating film can also pass through thermal transfer, either pressure transfer or water transfer, Huo Zhesan
Dimension surface, which is banded, forms decorating film on a surface 12 of metalwork 10.Decorating film, which is one layer, has color and/or pattern
Film, it is further to metalwork 10 to be modified, lift aesthetic feeling.
In other embodiment, alternatively, optical thin film can also use method physically or chemically in a table of metalwork 10
The dielectric film of layer of transparent, or plating layer of metal film are plated on face 12.Optical thin film is the uniform and thin medium of a layer thickness
Be attached to a surface 12 of metalwork 120, so can by the reflecting of optical thin film, (roll over) thoroughly and the characteristic such as penetrate and polarize, change
The transmission and reflection characteristic on the kind surface 12 of metalwork 10 1, makes the metallic luster of metalwork 10 further be lifted.
