System.
Reference picture 1, the coating membrane system include a stainless strip (SST), and it has corrosion resistance, and its back side is B, plating
Film surface is A.If stainless strip SST is only simultaneously by the surface treatment suitable for expected PVD plated films, then warp
Coated surface (A) should be just identified as by crossing that face being suitably surface-treated.If two faces of stainless strip (SST) are all
Similar or two sides is suitable for expected PVD plated films, then coated surface (A) can randomly choose.
Reference picture 1, adhesion layer (AL) is coated with stainless strip (SST) coated surface (A), can also select not to be coated with
This adhesion layer (AL).It is preferred that the adhesion layer (AL) that the chromium Cr by pure chromium Cr or slightly reacted with oxygen or nitrogen is formed.
Reference picture 1, above adhesion layer (AL) or directly above stainless strip (SST) coated surface (A), plate inhibition and generation
Compound coating (CL1).The compound coat (CL1) is made up of metal A and metal B mixture, and it is partly to complete
Reacted entirely with nitrogen N.Therefore the compound coat is (MeA using chemical formula:MeB)Nx.Here (MeA:MeB) it is metal A
Ratio between metal B, and metal A and metal B mixed proportion can be with simple metal A (100% MeA: 0% MeB)
It is leading, with simple metal B (0% MeA:100% MeB) for any ratio between leading or both.In chemical formula, Nx
Index X be reaction coefficient with nitrogen N.Reaction coefficient X can change between X=0 and X=1, and X=0 refers to 0% here
Nitrogen reacts and X=1 refers to 100% nitrogen reaction or meets the compound of demarcation stoichiometry.Herein, we use pure silicon
Si or silico-aluminum (Si/Al) or silicochromium (Si/Cr) deposit and created a compound layer (Cr as sputtering target material:
Si) Nx or (Cr:Si/Al) Nx or (Cr:Si/Cr)Nx.
Reference picture 1, another compound coat (CL2) can be coated with above the compound coat (CL1), can use with
Compound coat (CL1) identical mode is described to describe compound coat (CL2).Compound coat (CL2) applies with compound
The difference of layer (CL1) is that the ratio of each composition is different.The ratio difference of each composition can be the mixed of metal A and metal B
Composition and division in a proportion example (MeA:MeB it is) different or reaction coefficient X different either neither same.
Reference picture 1, above compound coat (CL1) and compound coat (CL2), additionally compound coat can be plating to
Compound coat (CLn), herein each coating need the component ratio different from inferior coatings and/or top coating.Can
To be metal A and metal B mixed proportion (MeA:MeB) different or reaction coefficient X is different, also or neither
Together.Here the n in CLn is the non-designated integer of applied compound coat quantity.The sum of applied compound coat can be with
It is the numeral of 1 or 2 or any other integer such as 3 or 4 or higher.These compound coats CL1, CL2 ... CLn shape
Into the sub- membrane system of absorbefacient inter coat (CL1-CLn) for establishing selective solar heat absorption coating.
Reference picture 1, can be extra above compound coat (CL1) or above the sub- membrane system of inter coat (CL1-CLn)
It is coated with a dielectric layer (DL).The dielectric layer (DL) uses silica SiO2, silicon nitride Si3N4 or its mixture
(SiOxNy), it has a sufficiently low refractive index, to suppress to reflect, strengthens absorbability.
Reference picture 2 and Fig. 3, Fig. 2 and Fig. 3 give compound coat CLn composition design schematic diagram.Each common sputtering
Technique includes a dual magnetron including sputtering target material A and sputtering target material B and configured.Sputtering target material A contains metal A or metal
Alloy A (MeA) and sputtering target material B contains metal B or metal alloy B (MeB).Each sputtering target material can pass through a technique
Rotation is operated alone independently of subsidiary target for power supply.Therefore produced from vapor stream flux (VA) caused by target A and target B
Vapor stream flux (VB) be different.One can be mixed to form newly by reaching two kinds of vapor stream flux (VA) on base material and (VB)
Film layer.By adding a reacting gas such as nitrogen N 2, the depositional coating can react and form a hybrid metal
Compound layer.Due to the arranged of sputtering target material and the angle of inclination in target orientation, corresponding vapor stream flux may
It will not be uniformly mixed.R (A+B) gives the total distributed of deposition on substrate surface.In this example, vapor stream flux
(VA) contribution is 60%, and the contribution of vapor stream flux (VB) is 40%.Apparent vapor stream flux (VA) is in R (A+B)
Contribution is higher.(RA) the deposition distribution of vapor stream flux (VA) is only embodied, and (RB) only embodies the heavy of vapor stream flux (VB)
Product rate distribution.It thus can be inferred that the gradient mixed between metal A (MeA) and metal B (MeB).This is not one
Individual problem, because it can be accounted for by the particular design to compound layer.It is appreciated that by this method,
The mean refractive index n and extinction coefficient k of compound layer can be drafted.Again by the arrangement of sputtering target material and arrangement and splash
The angle of inclination in material orientation of shooting at the target, the gradient of mixing can be adjusted.
The sputtering target material used in common sputtering technology can include alloying element, for example, aluminium Al in silicon Si to be formed
Si/Al or chromium Cr is in silicon Si to form Si/Cr.As long as chromium Cr or silicon Si are the decision elements of target, then the present invention just should
This includes the use of Cr alloy target materials and Si alloy target materials.
Reference picture 1 and Fig. 4, Figure of description 4 give the scheme of in general film plating process.The film plating process is suitable for
The plated film of the stainless strip (SST) of continuity reel-to-reel.Stainless strip (SST) is all austenites with corrosion resistance
Stainless steel alloy, 214 alloys and 304 alloys are for example there are here.

7000kg.And the web form that stainless strip needs to be wound into a roll is present.
Reference picture 1 and Fig. 4, before plated film, the surface of stainless strip (SST) must oil-free, without fat, free from dust and other
Pollutant.This can be handled to realize by carrying out degreasing, cleaning and heated-air drying to band before plated film, art technology
Personnel can complete above-mentioned plated film pre-treatment according to prior art, be not added with repeating herein.
