The present invention provides a kind of improved scheme coloured on hard substrate, the program is capable of forming a kind of aoxidize
The multi-layer film structure of color improves the conjugation power between coloring layer and substrate, improves the reliability coloured on hard substrate.
As shown in Figure 1, the multi-layer film structure of the heat-tinting includes basal layer 1, transition strengthening layer 2, aluminium layer 3 and oxygen
Change aluminium layer 31.The basal layer 1 is that substrate is wanted by taking the shell of electronic product as an example according to the difference of performance, appearance to product
It asks, can choose different materials as basal layer 1.Optionally, the basal layer 1 can be stainless steel, titanium, titanium alloy, magnesium
Alloy, amorphous alloy, aluminium alloy, copper alloy and ceramics, glass, plastic material, the present invention limit not to this.
The surface of the basal layer 1 is arranged in the transition strengthening layer, and transition strengthening layer 2 is for improving aluminium layer and basal layer
The case where conjugation power between 1, reduction aluminium layer and alumina layer fall off.Particularly, the transition strengthening layer 2 can be by one
Layer or multilayer transition material layer 21 and/or its compound layer 22 are constituted, can be according to the requirements of properties of product, the material of basal layer 1
The factors such as material select design transition strengthening layer 2 to have several layers of structures, using which kind of material.It should be noted that the transition material
Material needs can have good conjugation power with basal layer 1 and aluminium layer, so, in the solution of the present invention, transition material is
There is titanium, zirconium, chromium, nickel, tungsten, aluminium, zinc, carbon and the silicon of good bond active force with most of hard materials, transition material can be with
One of above-mentioned nine kinds of materials are at least selected, the present invention is defined not to this.The transition material layer 21 can be transition material
The film layer formed through vapor deposition, transition material compound layer 22 can be the film that transition material is formed after vapor deposition is handled
Layer.
The aluminium layer 3 is arranged on the surface of the transition strengthening layer 2, and aluminium layer 3 suitably forms alumina layer, by coloring
Processing is capable of forming different colours.So the present invention forms aluminium layer 3 as formation on transition strengthening layer has different colours
The basis of alumina layer.The transition strengthening layer primarily serves the effect for improving conjugation power between aluminium layer and basal layer.
The alumina layer 31 is formed on the surface layer of the aluminium layer 3, the aluminium layer 3 through peroxidating and coloring treatment,
The alumina layer 31 can be formed on surface layer.The present invention is not limited in the technique for aoxidizing and colouring on aluminium layer and limits
System after forming aluminium layer 3 on transition strengthening layer 2, can carry out oxidization electrolysis by dilute sulfuric acid and form oxidation in one case
Aluminium later again dyes aluminium oxide with dyestuff, forms alumina layer;Alternatively, in other embodiments, to the oxygen of aluminium layer
Change processing can pass through one or more electricity such as sulfuric acid, phosphoric acid, oxalic acid, boric acid, tartaric acid, lactic acid, malic acid, sulfo group organic acid
Solution liquid is mixed to form the alumina layer of natural coloring oxidation, hard anodizing or differential arc oxidation effect, improves material surface not
With color can be decorative.
The multi-layer film structure of heat-tinting provided by the invention can effectively enhance aluminium layer and alumina layer is attached to substrate
The case where adhesive force on layer, reduction aluminium layer and alumina layer fall off.So that frequently with various hard materials as substrate
In the case where layer, in the attached substrate material that aluminium layer and alumina layer can be stable.Below by way of several specific embodiment parties
The present invention will be described for formula.
Optionally, in one embodiment, as shown in Figure 1, the transition strengthening layer 2 may include one layer of transition material
The compound layer 22 of layer 21 and one layer of transition material.The transition material layer 21 is set up directly on the surface of the basal layer 1, into
One step, it is handled by vapor deposition, the change of transition material can be formed in the surface of the transition material layer 21 or entirety
Close nitride layer 22.The aluminium layer 3 is then arranged on the compound layer 22 of the transition material.
Optionally, in another embodiment, as shown in Fig. 2, the transition strengthening layer 2 may include two layers of transition material
The chemical combination layer of the bed of material 21 and two layers of transition material layer 21.Wherein, first layer transition material layer 21 is set up directly on the basal layer 1
Surface on, and the compound layer 22 of remaining transition material and transition material layer 21 then successively, interval setting in first layer
On transition material layer 21.
Transition material layer forms transition material compound layer disposed thereon after chemical combination is handled.And in transition material
The new transition material layer re-formed on nitride layer is closed, can be using another material, it can also be using the transition material with lower layer
The identical material of the bed of material is formed.
Optionally, in one embodiment, the basal layer 1 is stainless steel layer, and the transition strengthening layer 2 includes one layer
The compound layer 22 of transition material layer 21 and one layer of transition material.The transition material layer 21 is titanium film layer, and the titanium film layer is logical
Vapor deposition is crossed to be attached on the basal layer 1.The compound layer 22 of transition material is titanium nitride film, and the titanium nitride film is logical
Gas-phase deposition is crossed to be formed on the titanium film layer.By controlling technological parameter, adjustable titanium nitride film is in titanium film layer
On thickness.In this embodiment, to guarantee to provide good conjugation power, the thickness of the titanium film layer is preferably 5
Micron, the thickness of the titanium nitride film is then 1 micron.
Optionally, in another embodiment, the basal layer 1 can be the titanium-based formed by pure titanium or titanium alloy
Layer, the transition material layer 21 then can be titanium film layer or zirconium film layer, and transition material layer 21 is attached to by gas-phase deposition
In titanium-based layer surface.Similarly, the compound layer of the transition material then can be the titanium nitride formed through gas-phase deposition
Layer or zirconium nitride film layer.Preferably, the thickness of the transition material layer can be 3 microns, and the transition material compound layer is then
It can be 2 microns.
