Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with specific embodiments, but not limited to specific examples.

[0011] The specific implementation steps of the preparation method of the yttrium silicate coating with oxidation resistance are as follows:

[0012] 1. Prepare yttrium silicate powder. The method is: select Y(NO with a molar ratio of 5:2.5:8 3 ) 3 , Na 2 SiO 3 , NaOH, after stirring, all of them were transferred to the ultrasonic generator, acted on 300W power for 60 minutes, then dried at 60°C for 10 hours, and finally cooled for 2-3 hours.

[0013] 2. Set the density to 1.7g / cm 3 The 2D-C / C composite material is cut into small pieces, and then the sharp corners are firstly ground with 100# sandpaper, and then polished with 400# sandpaper, cleaned with ethanol, and dried in a drying oven.

[0014] 3. The prepared yttrium silicate powder is subjected to ultrasonic vibration and magnetic stirring to obtain a suspension. ...

Abstract

The invention provides a preparation method of an yttrium silicates coating having the oxidation resistance, the method adopts a novel hydrothermal electrophoretic deposition technique to prepare the yttrium silicates coating with oxidation resistance, and the method has the advantages of high efficiency, low manufacturing cost, good coating compactness and excellent oxidation resistance of the coating.

Description

1. Technical field: [0001] The invention relates to a preparation method of a composite material coating, in particular to a preparation method of an yttrium silicate coating with oxidation resistance. 2. Background technology: [0002] Carbon / carbon composites are widely used in aerospace because of their excellent high-temperature mechanical properties and outstanding thermal shock resistance. However, carbon / carbon composites begin to oxidize in an aerobic environment exceeding 370 °C, which limits their wide application as high-temperature protection or anti-ablation materials in oxidizing atmospheres. In order to improve the oxidation resistance of carbon / carbon composites, coating technology is mainly applied. At present, the methods for preparing yttrium silicate coatings that have been developed to a certain extent mainly include plasma spraying method, slurry method and in-situ synthesis method. Coatings prepared by these methods are deficient in efficiency and co...
