Description
Technical field
The utility model relates to a kind of carbon material high-temperature oxidation resistant field, specifically a kind of carbon material oxidation resistant coating, and particularly relating to a kind of is the surface oxidation-resistant coating of matrix by carbon/carbon compound material or graphite material.
Background technology
Carbon/carbon compound material is one of advanced composite material of present widespread use, a series of good performances such as this material light specific gravity, anti-ablation, corrosion-resistant, antifriction sassafras, mechanical behavior under high temperature are good, it is the optimal candidate material of high temperature rub resistance parts and thermal structure spare, being widely used in the Aeronautics and Astronautics field, is one of the high-temperature structural material of tool potentiality of 21 century.Yet there is a fatal shortcoming in carbon/carbon compound material, and the performance of many excellences only could keep under inert atmosphere and vacuum environment.Studies show that, carbon/carbon compound material in air 370 ℃, in water vapor 650 ℃, at CO
2In 750 ℃ just begin oxidation, and oxidation rate increases rapidly with the rising of temperature, causes material oxidation weightlessness, and its intensity is reduced even total loss significantly, finally causes the destructive destruction of material, limited being extensive use of of carbon/carbon compound material.Therefore, how to solve the carbon/carbon compound material high-temperature oxidation resistant and become one of the hot issue in carbon/carbon compound material field.According to the mechanism of carbon/carbon compound material oxidation, the anti-oxidant measure of carbon/carbon compound material at present mainly is divided into two classes: inner anti-oxidant and top coat.At present, inner anti-oxidation tech is mainly used in the oxidation protection below 1000 ℃.In order to solve the anti-oxidant problem of carbon/carbon compound material more than 1000 ℃, the researchist has carried out a large amount of fruitful researchs to the top coat technology of preparing both at home and abroad, has developed multiple oxidation resistant coating.
It is bigger that SiC has unreactiveness, the excellent high-temperature mechanical property, and thermal shock resistance and resistance of oxidation, high fusing point, and also the reaction of SiC high temperature oxidation can generate continuous, even, fine and close SiO
2The oxidation protection film is so SiC coating and SiC compound coating are the preferred material of carbon/carbon compound material and graphite material high-temperature oxidation resistant coating.But the oxidation-protective effect of SiC coating that develops at present and SiC compound coating is far away from theoretical value, and its major cause is well not resolve the structure problem of coating.
Document 1: application number is 200910022719.4, publication number is CN101565328A, denomination of invention is that the preparation method's of carbon/carbon compound material inoxidzable coating patent application discloses a kind of employing entrapping method and prepares the SiC transition layer, utilizes the supersonic speed plasma spraying equipment with MoSi

Document 2: " A multilayer coating of dense SiC alternated with porous Si-Mo for the oxidation protection of carbon/carbon silicon carbide composites; Carbon; 2008,46(1): P149-P153 " introduced the method that a kind of chemical Vapor deposition process and slurry process prepare the SiC/Si-Mo compound coating.At first, utilize slurry process to prepare porous Si-Mo coating then, so repeated multiple times at the SiC coatingsurface in carbon/carbon composite material base surface CVD SiC coating.
The method of document 1 and document 2 discloses by prepare the method for one deck SiC transition layer or Si-Mo porous coating between carbon/carbon composite material base body and skin, makes it to play part and alleviates carbon/carbon composite material base body and MoSi
2The perhaps unmatched problem of SiC thermal expansivity.But because the defective of entrapping method and slurry process self, the associativity of the coating of preparation and carbon/carbon composite material base body is relatively poor, and transition layer comes off easily, thereby the thermal shock resistance of whole coating is still not ideal enough.
Silicon carbide whisker is that a kind of diameter is an extremely micron-sized single crystal fibre of nano level, has good characteristics such as high strength, high rigidity, high elastic coefficient and density are low, corrosion-resistant, chemical property stable, oxidation-resistance property is strong.In preparation hot metal base, ceramic matric composite, be widely used.In recent years, for solving the easy rimose problem of carbon/carbon compound material high-temperature oxidation resistant coating, silicon carbide whisker is used as the preparation that toughening material is used for high-temperature oxidation resistant coating.
Document 3: the patent No. is 200610041916.7, Granted publication number is CN1321092C, denomination of invention be carbon/carbon compound material surface oxidation-resistant multiple phase coating the preparation method patent disclosure a kind of employing slurry process prepare the crystal whisker toughened coating of one deck porous SiC, adopt entrapping method preparation to have the MoSi of the carbon/carbon compound material of the crystal whisker toughened coating of SiC again
2Top coat.
Document 4: " SiC whisker-toughened SiC oxidation protective coating for carbon/carbon composites; Carbon; 2006; 44(3): P602-P605 " introduced a kind of slurry process that utilizes and prepared silicon carbide whisker toughening silicon carbide internal layer, and then the top layer for preparing the silicon carbide whisker toughening silicon carbide with entrapping method.
The method of document 3 and document 4 discloses the method that silicon carbide whisker is applied to coating, but, its silicon carbide whisker mixes by the artificial mode and enters coating system, its distribution certainly exists certain ununiformity, simultaneously, the crystal whisker toughened coating of this doped silicon carbide can only one-side raising coating self resistance of oxidation, and improve hot expansibility between coating and the carbon/carbon composite material base body do not match aspect effect very little, and the latter often is only the key that causes coating to ftracture easily and come off, and, owing to adopt several different methods to prepare coating, objectively cause preparation technology of coating complicated, be unfavorable for the reduction of cost, influence is promoted the use of.
Graphite material has many good performances, extensively because fields such as metallurgy, machinery, electrical equipment and chemical industry, it is the important materials of nuclear industry, yet graphite material begins oxidation under the oxidizing atmosphere of temperature more than 400 ℃, and oxidation rate is accelerated more than 800 ℃, very easily ablate with oxidizing gas generation chemical reaction, influenced the work-ing life of graphite, in order to improve the oxidation-resistance of graphite material, document 5: " SiC/Si-MoSi
2The preparation of oxidation resistant coating and performance study, refractory materials, 2006,40(1): P161-P165 " preparing the SiC/Si-MoSi2 oxidation resistant coating at graphite surface; be raw material with the Si powder at first, adopt entrapping method to prepare the SiC internal layer, is raw material with Mo powder and Si powder; be mixed with the slip that m (Mo): m (Si) is respectively 1:5,1.5:5,2:5 and 2.5:5 then, adopts the slip sintering process to prepare Si-MoSi
2Outer.Because the defective of entrapping method and slurry process self, the associativity of the coating of preparation and graphite material matrix is also relatively poor, and transition layer comes off easily, thereby the oxidation-resistance of whole coating and thermal shock resistance are still not ideal enough.
