Abstract
The invention discloses a high-temperature alloy glass mold. The mold comprises a base having cambered molding surface, one protection film is compounded on the molding surface, and the protection film is a composite oxide coating. Compared with the prior art, the invention has the following advantages that one composite oxide coating is compounded on the cambered molding surface of the base as protection film, the composite oxide coating has good high-temperature resistance, improved hot corrosion resistance and higher oxidation resistance and wear resistance, and the prepared high-temperature alloy glass mold has good chemical stability, strong thermal impact resistance, high mechanical strength and excellent demolding property.
Description
Technical field
The invention discloses a kind of superalloy glass mold.
Background technology
The compression molding processing procedure of glassy product; Particularly make the opticglass product; Like aspheric surface glass lens, globe lens, prism etc.; But adopt direct compression molding technology direct production opticglass product; Need not subsequent process steps such as polishing, polishing; Can enhance productivity greatly and output, and good product quality.But directly compression molding method requires very high for the chemical stability of mould, thermal shock resistance, physical strength, demolding performace etc.In fact the development of compression molding technology depends primarily on the progress of moulding stock and mould structure.Mould for compression molding generally has following requirement:
1), when high temperature, have good rigidity, anti-mechanical impact strength and enough hardness;
2), do not crack and be out of shape in reaching rapid heating refrigerative thermal shocking bed die repeatedly;
3), chemical reaction does not take place in die surface and opticglass when high temperature, does not adhere to glass;
4), high temperature oxidation does not take place;
5), good processability, be prone to be processed into the profile of high precision and high surface finish;
6), die life is long, and then reduce cost.
Traditional moulds adopts stainless steel or refractory alloy as moulding stock mostly, and high temperature oxidation takes place this mould easily, under thermal shocking effect repeatedly, grain growth can take place, thereby glass is cohered in the die surface roughen.
Summary of the invention
To above-mentioned defective, the object of the invention provides the superalloy glass mold that a kind of chemical stability is good, thermal shock resistance is strong, physical strength is high, demolding performace is good.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of superalloy glass mold of the present invention, said mould comprise a matrix with molded of arcuation, are compounded with layer protecting film on said molded, and said protective membrane is a composite oxide coating.
In a kind of preferred embodiment of the present invention, the concrete composition of said composite oxide coating is: 3 ~ 5% ZrO
2, 10 ~ 45% Al
2O
3, 10 ~ 15%ZnO, 2 ~ 5%CaO, 3 ~ 6%B
2O
3, 3 ~ 6%Na
2O, 5 ~ 8%K

2
In a kind of preferred embodiment of the present invention, said protective membrane thickness is 10 ~ 40 μ m.
In a kind of preferred embodiment of the present invention, said matrix is a superalloy.
In a kind of preferred embodiment of the present invention, also comprise tack coat between said matrix and the protective membrane with the matrix identical component.
In a kind of preferred embodiment of the present invention, the thickness of said tack coat is 2-8 μ m.
The present invention compared with prior art has the following advantages: molded of matrix arcuation is gone up compound one deck composite oxide coating as protective membrane; It is good that composite oxide coating has resistance to elevated temperatures; Have improved corrosion and heat resistant property simultaneously, and the higher oxidation-resistance and the type that resistance to wears.Made superalloy glass mold chemical stability is good, thermal shock resistance is strong, physical strength is high, demolding performace is good.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present invention;
Wherein: 1 is matrix, and 11 is molded, and 2 is protective membrane, and 3 is tack coat.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
As shown in Figure 1; Superalloy glass mold in the present embodiment is made up of matrix 1 and protective membrane 2; Matrix 1 has molded 11 an of arcuation; Said protective membrane 2 is compounded on molded 11 through tack coat 3; Said matrix 1 is preferably superalloy; Said tack coat 3 is preferably the superalloy congruent with matrix 1, and said protective membrane 2 is a composite oxide coating.
Embodiment one:
Said matrix is processed for the IN783 superalloy, uses arc ion plating manufactured one deck and the congruent tack coat of IN783 superalloy matrix molded of sample matrices, and thickness is 5 μ m.Be 5% ZrO then with composition quality per-cent
2, 45% Al
2O
3, 15%ZnO, 5%CaO, 6%B
2O
3, 6%Na
2O, 8%K
2O, all the other are SiO
2Composite oxides be sprayed at tie layer surface, and reach the thickness of 30 μ m, after high temperature sintering.Process composite oxide coating.
Finished product has been compared following advantage with common IN738 superalloy: generate with Cr during the oxidation of IN738 superalloy
2O
3Be main mixed oxidization film, it is poor at antioxidant property more than 1000 ℃, and finished product of the present invention is good at antioxidant property more than 1000 ℃, and 100 hours gains in weight of oxidation are little, and coating is not seen yet and come off.
The above; It only is the specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed; Variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
