Brief description of the drawings
Fig. 1 is the flow chart that PVD aura of the present invention aoxidizes ornamental film plating process.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text Word can be implemented according to this.
As shown in figure 1, the present invention, which provides a kind of PVD aura, aoxidizes ornamental film plating process, including：
Step 1: provide the a* values section and b* values section of aim colour；
One layer of primary colours film layer with certain color is formed Step 2: being deposited using PVD method on work surface, and Make the 10% of the a* values at least up to lower limit in the a* values section of aim colour of the color of the primary colours film layer, and the primary colours film The a* values of the color of layer are no more than the 90% of the higher limit in the a* values section of aim colour, make the b* values of the color of the primary colours film layer At least up to the 10% of the lower limit in the b* values section of aim colour, and the b* values of the color of the primary colours film layer are no more than aim colour B* values section higher limit 90%；
Step 3: carrying out oxidation reaction in the primary colours film layer using aura oxidizing process, glow discharging process is controlled And the progress of the oxidation reaction, so that the a* values of the color of the oxidation film layer formed fall into the a* values area of the aim colour Between, the b* values of the color for the oxidation film layer to be formed is fallen into the b* values section of the aim colour.
The present invention first quantifies aim colour, and is represented with a* values and b* values, is processed afterwards using PVD method with certain face The primary colours film layer of color, and the a* values of the color of primary colours film layer and b* values is met set condition；Afterwards, aura oxygen is utilized Change method carries out oxidation reaction, i.e. oxygen glow discharge in primary colours film layer, oxidation reaction occurs with primary colours film layer, and generate oxygen Change film layer, the oxidation film layer has required aim colour.In oxidizing process, the color of film layer obtains positive intensification, most The aim colour of product is formd eventually.Wherein, aura oxidizing process refers to non-electric arc deposited oxide method, and it is high partially in loading to refer to the oxygen being passed through During pressure, oxygen ionization glow discharge is produced, and then aoxidizes primary colours film layer, so as to form oxidation film layer.
For example, when the a* values of the color of primary colours film layer reach the 10% of the lower limit in aim colour a* values section, step In three, when controlling oxidation reaction to carry out, as long as ensureing that the a* values of oxidation film layer reach the lower limit in aim colour a* values section, just Meet the requirements；And in the 90% of the higher limit that the a* values of the color of primary colours film layer are aim colour a* values section, step 3, controlling When oxygenerating reaction is carried out, as long as the a* values for ensureing oxidation film layer are the higher limit in aim colour a* values section, just meet the requirements.
Product film layer different faces and different parts color obtained by the present invention are uniform, with heat product colour difference compared with It is small, effectively improve product two tone colour, the even phenomenon of irregular colour；Simultaneously effective improve the anti-chemical experiment anti-corrosive properties of film layer Can, reach the antiseptic effect that traditional PVD coating methods do not reach；Technique is simple, and different heat technological parameter differences are small, and technique is steady Qualitative height, practical operation are easier to control；Yields is higher, and production efficiency is high, reduces equipment capacity load, reaches energy-conservation drop Consumption, shorten the production cycle, quickly reach the demand of client, effectively save artificial, power source, material cost, machine utilization subtracts Few, fault rate declines.
In a preferred embodiment, described PVD aura is aoxidized in ornamental film plating process, in the step 1, The a* values of the aim colour are more than 0, b* values and are more than 0.
Further, the of a relatively high color film of the a* values made suitable for making traditional handicraft be difficult to and b* values of the invention Layer.
In a preferred embodiment, described PVD aura is aoxidized in ornamental film plating process, the work surface For metal surface.
The present invention is applied to decorating plated product, and such as bathroom, clock and watch hardware products is processed.
In a preferred embodiment, described PVD aura is aoxidized in ornamental film plating process, in the step 2, Deposited using PVD method on work surface and form one layer of primary colours film layer with certain color, and make the primary colours film layer Color a* values be at least up to aim colour a* values section lower limit 20%, and a* values of the color of the primary colours film layer No more than the 50% of the higher limit in the a* values section of aim colour, the b* values of the color of the primary colours film layer are made to be at least up to aim colour B* values section lower limit 60%, and the b* values of the color of the primary colours film layer be no more than aim colour b* values section it is upper The 80% of limit value.
When the a* values and b* values of the color of primary colours film layer are set according to aforementioned proportion, follow-up aura oxidation step is easier Aim colour required for being formed, helps to simplify technique, reduces the difficulty of subsequent step.Such as the a* values of the color of primary colours film layer It is small (such as less than aim colour a* values section lower limit 20%), then easily cause the setting of the technological parameter in subsequent step Difficulty increases, and influences technology stability；As the a* values of the color of primary colours film layer are excessive (such as upper higher than aim colour a* values section Limit value 50%), also easily influence technology stability.
In a preferred embodiment, described PVD aura is aoxidized in ornamental film plating process, in the step 3, The progress of glow discharging process and the oxidation reaction is controlled, there is process to be for it：Control participates in the oxygen of glow discharging process Tolerance, it is 1.0 × 10 to control vacuum0~2.0 × 100Pa, bias as 500V~600V, control glow time.
By controlling the progress of glow discharging process and oxidation reaction, i.e., specifically control amount of oxygen, vacuum, bias are big Small and glow time, forward direction deepen the color of primary colours film layer, so that the oxidation film layer ultimately formed obtains aim colour.
In a preferred embodiment, described PVD aura is aoxidized in ornamental film plating process, in the step 2, The a* values of the color of the primary colours film layer are the 30% of the a* values of aim colour.
In a preferred embodiment, described PVD aura is aoxidized in ornamental film plating process, in the step 2, The b* values of the color of the primary colours film layer are the 70% of the b* values of aim colour.
