Description
Technical field
The present invention relates to a kind of preparation methods of oxidation-resistant ceramic coating.
Background technique
Graphite material and other carbon-based materials, such as C/C composite material have a variety of excellent performances, but in high temperature
It is easy to oxidize under the conditions of oxygen-containing, significantly limit its application range.In order to meet graphite material in high-temperature oxidation environment
Requirement, it is necessary to improve its antioxygenic property.
Currently used for improve Oxidation Resistance of Graphite Material main path there are two types of.One is matrix modifications, i.e., in stone
Antioxidant is added in black matrix reduces the oxidation rate of material；Another kind is surface coating method, i.e., graphite material surface applies
One layer of antioxidant coating is covered, opens it with oxidizing gas isolation, prevents gas from entering to improve antioxygenic property.
For ZrB2- SiC base ceramic material, with excellent high-temperature oxidation resistance.Due to ZrB2It is basic with SiC
It constitutes, which all has good antioxygenic property within the temperature range of from room temperature to 1600 DEG C.Therefore, ZrB2-
The composition of SiC is suitable for use as the composition material of fire-resistant oxidation resistant coating.But ZrB2SiC ceramic is difficult to be sintered, and is preparing
It is difficult to obtain fine and close structure during coating, limits its application as antioxidant coating.Currently, common preparation
ZrB2The method of-SiC coating is to prepare one layer of SiC transition zone using investment, then passes through investment, thermal spraying, brushing etc.
Method further prepares outer coating.In order to further increase ZrB2- SiC coating antioxygenic property generally requires to combine a variety of
Method prepares laminated coating.Preparation process is more complex, and the period is longer, higher cost, and most method be difficult to be suitable for for
The component of special shape.
Summary of the invention
Invention provides a kind of ZrB with good oxidation resistance energy2-SiC-B2O3-SiO2- Zr(H3PO4)2It applies
The preparation method of layer.
ZrB of the invention2-SiC-B2O3-SiO2-Zr(H3PO4)2The preparation method of coating is to sequentially include the following steps:
By ZrB2, SiC, B2O3、SiO2, H3PO4 be configured to slurry, then by brush in the way of by slurry brush in graphite material
Surface, the brush second layer again as needed after drying at room temperature.So continue, brushes laminated coating as needed.
In the method, the volume ratio of ZrB2 and SiC should be between 1:9 ~ 9:1.B2O3And SiO2Molar ratio in 1:4 ~ 2:
Between 1.B2O3And SiO2Volume content be no more than ZrB2 and SiC total volume 50%.H3PO4 concentration 1wt% ~ 85wt% it
Between, the ratio between gross mass of the quality of H3PO4 used and mixed powder is between 1:10 ~ 20:1.
Advantages of the present invention:
One, ZrB of the invention2-SiC-B2O3-SiO2-Zr(H3PO4)2Preparation technology of coating is simple, easy to use, can be direct
Using spread coating in component surface prepares coating, and coating layer thickness can according to need and be adjusted by the method repeatedly brushed
Section.Slurry viscosity is adjustable, passes through the thickness of the adjustable signal layer coating of adjusting of viscosity.The coating uses spread coating, fits
For basis material of various shapes.
Two, ZrB prepared by the present invention2-SiC-B2O3-SiO2-Zr(H3PO4)2Coating structure is fine and close, after brushing just through drying
It can be used for hot environment, be not required to using preceding carry out high-temperature process.Coating after drying has good in high-temperature oxidation environment
Antioxygenic property, can be used for a long time in 1500 DEG C of high-temperature oxidation environment.

Specific embodiment
A kind of ZrB in present embodiment2-SiC-B2O3-SiO2-Zr(H3PO4)2The preparation method of coating is according to the following steps
It carries out:
By 42g ZrB2、9.6g SiC、2.5g B2O3、2.6g SiO2It is added in ball grinder, ethyl alcohol is added as ball-milling medium,
Then it is mixed using ball mill, utilizes rotary evaporator that will cross 200 mesh after the mixture drying of the above powder after mixing 8h
Sieve.Then the powder obtained after mixing is mixed with the ratio that 10g powder corresponds to 4ml concentrated phosphoric acid, phosphoric acid concentration 85%.
The powder that phosphoric acid is added is sufficiently stirred, powder and phosphoric acid are sufficiently mixed, the slurry of mixed powder is made.Pass through brushing
Method slurry is brushed after graphite matrix shows, at room temperature it is dry for 24 hours.Then second is carried out on its surface to brush
Painting prepares second layer coating, then dry for 24 hours in room temperature condition.It so repeats, until four layers of coating are made.
Coating after brushing is after drying at room temperature, and coating structure is fine and close, with substrate combinating strength height.Fig. 1 show room
ZrB after temperature is dry2-SiC-B2O3-SiO2-Zr(H3PO4)2The surface SEM photograph of coating.Through peroxophosphoric acid treated coating knot
Structure is fine and close, and there are a large amount of glass phases.Due to the use of concentrated phosphoric acid, Zr (H is formd in coating3PO4)2, it is also possible to it forms
SiHP3O10.The presence of glass phase substantially increases coating consistency, and consistency coating can be effectively by matrix and external oxidation ring
Border separates.
By four layers of ZrB obtained2-SiC-B2O3-SiO2-Zr(H3PO4)2It is heated to 1500 DEG C in the air of coating, and protects
After warm 60min, coating structure keeps complete, is effectively protected graphite matrix, avoids the oxidation of graphite matrix.After oxidation
Coating macro morphology is as shown in Fig. 2, the diameter of disc-shaped graphite matrix therein is 50mm.
