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. ...
