Description
Technical field
The present invention relates to a kind of preparation method of carbon/carbon compound material top coat, be specifically related to the preparation method of the anti-oxidant phosphate glass coating of a kind of carbon/carbon compound material.
Background technology
The C/C matrix material is to be the thomel or the graphite fibre enhanced material of matrix with carbon; Its integral system by carbon form [Liu's Bin, Yi Maozhong .C/C matrix material anti-oxidation composite coatings such as Xiong Xiang preparations and performance [J] thereof. mining metallurgical engineering; 2000,20 (8): 74-76].Because the C/C matrix material has light specific gravity, big, the anti-ablation of specific tenacity, wear resistance and advantages such as good high-temperature mechanical property and thermal property; Therefore be widely used in the fields such as end cap, rocket nozzle and aeroplane brake discs of aerospace, intercontinental missile; Demonstrate great meliority [Cheng Jiwei, Luo Ruiying, Wang Tianmin. carbon/carbon composite high-temperature oxidation resistant present Research [J]. the plain technology of charcoal; 2001,116 (5): 28-33].But rising along with use temperature; The C/C matrix material is prone to be oxidized into " bottleneck " of its application; Under the environment that aerobic exists, when temperature was higher than 400 ℃, oxidation can take place in carbon/carbon composite; Its intensity reduces even total loss significantly, has limited the application of (more than 1300 ℃) in the high temperature field of C/C matrix material.
At present the measure that prevents the oxidation of C/C matrix material is mainly concentrated on following two aspects: the one, inner anti-oxidation technology.Mainly be that thomel is carried out antioxidation treatment and the matrix of C/C matrix material is improved.The 2nd, the exterior coating anti-oxidation tech.Prepare single or compound coating is prevented that block diffuses into oxidation is taken place in the matrix through outside, thereby improved high-temperature oxidation resistance at the C/C matrix material.
Often single coating can not satisfy the long-time oxidation resistant requirement of carbon/carbon compound material; Therefore multi-layer composite coatings becomes the preferred option that people solve the carbon/carbon compound material high-temperature oxidation resistant; General multi-layer composite coatings is the compound coating of ceramic coating and glass coating, because the matrix and the thermal dilation difference between the coating of ceramic coating can form defectives such as tiny crack in coating, makes antioxidant property meeting variation; And at high temperature having characteristics such as LV and wettability and thermostability, glass coating fills up defective [Huang Jianfeng such as these tiny cracks; Li Hejun, Xiong Xinbai etc. the progress of carbon/carbon composite high-temperature oxidation resistant coating [J]. novel charcoal material, 2005; 20 (4): 373-379], the oxidation resistance temperature of C/C matrix material is greatly improved.Because SiC ceramic coating and matrix have the thermal expansivity that is complementary, and generate SiO after the oxidation
2Can better inhibited matrix carbon to external diffusion, be widely used in the undercoat of C/C matrix material ORC.Top coating adopts the phosphate glass coating, and phosphide mainly contains two to the restraining effect of C/C matrix material high temperature oxidation: one is that physics hinders, and another kind is that active site hinders; The key factor that keeps retarding effect during the existing of the existence of the oxo bridge key in the glass coating and P contained compound; To C/C matrix material oxidation phosphide glass be effective external surface coating [Hu Xinghua, Wu Ming platinum are looked into celebrating virtue. the anti-oxidant progress of carbon/carbon composite [J]. charcoal is plain; 2006,127 (3): 38-45].
At present, being used for oxidation resistant glass coating mainly is borate glass series and phosphate glass.The staple of borate glass is B
2O
3, because B
2O
3In wet environment, have higher susceptibility and volatility, and along with temperature its wettability that raises also can reduce, these drawbacks limit the application of borate glass coating in the aerobic environment more than 1000 ℃.Though people improve borate glass, still can't satisfy the application under 1500 ℃ of this extreme temperatures.
Summary of the invention
It is that transition layer, phosphate glass are the preparation method of the anti-oxidant phosphate glass coating of carbon/carbon compound material of top coating with silit that the object of the invention proposes a kind of.Preparation technology of the present invention is simple, and cost is low, and the production cycle is fast, is fit to carry out scale operation, and even through the compound coating thickness of the present invention's preparation, and flawless in conjunction with firmly, has the good high-temperature antioxidant property.
