Description
Technical field
The present invention relates to artwork Ornament technical fields, and in particular to a kind of artwork Ornament and its system with true color separation macular area
Make method.
Background technique
So that artwork Ornament surface is formed different colour contrasts by color separation, its decorative effect can be obviously improved.According to
Whether the basic material at color separation position is consistent, and color separation can be divided into two class of true color separation and false color separation.True color separation refers to different colours point
The basic material in area is inconsistent, the contrast effect formed due to the color of each material itself has differences；And false color separation refers to not
It is consistent with the substrate material of color subregion, only in surface different zones form different color with the methods of physics, chemistry and
Obtain color separation contrast effect.
Currently, the technique that the production of color-dividing process ornaments mainly based on false color separation, forms false color separation mainly has physics gas
Mutually deposition, plating, chemical plating etc., their main making steps are, first by the surface varnish at positions certain on artwork Ornament
Equal materials closing carries out color plated film in unclosed region, removes closed varnish after the completion of plated film, and plating color film
Surface coating varnish closing, then carry out the plated film of another color in non-coating film area again.Thus two kinds or more can be formed
Kind colour contrast, obtains color separation effect.But the outstanding problem of such methods be only formd on artwork Ornament surface it is very thin
Color film layer, in use, color film layer be easy to wear and lose color separation effect.
When making the artwork Ornament of true color separation, it is common practice to make two different colors of component respectively, then
Again by soldering by their Combination Weldings to together, due to needing to weld under atmosphere using cored solder when being brazed, thus weld seam
After Qu Jing polishing other than being easy to show the colour contrast of solder, also often sand hole defect is welded in exposure, to significantly affect
The appearance of artwork Ornament.In addition, the faying face of this welding can only generally be made into simple plane, if to form complexity
The faying face of decorative pattern, then very high to the processing cooperation required precision of component faying face, otherwise solder is easy to accumulate at gap,
Seriously affect appearance.It is had carried out some research in terms of the true color separation technology for not using cored solder in recent years, but it is basic
It is the report in terms of cheap metal.For example, CN201810163323.0 discloses a kind of true color separation ring-type ornaments and its assembly side
Method, it makes at least two metal ring ornaments parts, they is placed in mold and is limited, and then passes through cold extrusion for component
Pressure is assembled together to form color separation；But the effect of this method acquisition is not color separation truly, after cold extrusion
There are visible gaps between two metal ring ornaments parts, and excessively high extruding force will cause the deformation of component, and different materials
The part distortion degree of matter is also inconsistent.CN201220683349.6 discloses a kind of true color-separation ring, it passes through the first circle body
It is joined together to form groove with the second circle body, then is embedded in the third circle body of different colours and color separation effect in groove；But
This method is using cold machinery complex method, and in junction, difference avoids the occurrence of gap, and the intensity of connection is also limited.
CN201711338381.4 discloses a kind of production method of true color separation mokume gane, it uses red copper compound, brass compound
With copper-nickel alloy compound, by material saw cutting it is uniform after, heat welded in electric cellar furnace is placed on by Interal fixation with bolt, it is then right
The sheet metal of welding carries out annealing and forges to form color separation striped；But this technique will make to be formed between the metal of unlike material
The metallurgical bonding of uniform, controllable and color subregion are extremely difficult, and reason is: first is that this mode will form metallurgical bonding
Welding effect, the control of fusing point and heating temperature to material requires especially tight, there is no real welding when temperature is slightly relatively low,
It is easy to happen cracking in forging below, being easy to melt in junction again when temperature is slightly higher leads to colour mixture；Second is that molten
In termination process suitably pressurization to it is intermetallic it is compound be beneficial, but this mode is pressurizeed using bolt, the pressure of application
Power is very limited, and bolt enters in furnace together with metal to be composite and heated, and bolt is also heated swollen in the process
It is swollen, relative constant pressure cannot be improved for metal composite, therefore the pressure being subject between metal is weaker, be unfavorable for the molten of them
It connects, and bolt is serious by high-temperature oxydation, dismantling is difficult；Third is that being heated under atmosphere for a long time, between metal seams inevitably
Oxidation occurs and influences bond strength.
Summary of the invention
It is an object of the invention to provide a kind of technique with true color separation macular area in place of overcome the deficiencies in the prior art
The obtained artwork Ornament color separation contrast of ornaments and preparation method thereof, this method production is obvious, and color macular area random distribution is different
