Embodiment 1
[0028]Step 1: Prepare SiC inner coating. The specific process is:
[0029] 1) The C / C composite material was polished and polished sequentially with No. 400, No. 800 and No. 1000 sandpaper, then ultrasonically cleaned with absolute ethanol, and dried in an oven for later use. The drying temperature is 80°C.
[0030] 2) Weigh 80g of Si powder, 30g of C powder, and 5g of Al respectively 2 o 3 The powder was placed in a turpentine ball mill jar, and agate balls of different numbers and diameters were put into the ball mill jar and mixed for 2 hours to obtain a mixed powder, which was dried and used as an embedding material for later use.
[0031] 3) Put half of the prepared mixed powder into the graphite crucible, then place the cleaned and dried C / C composite material sample on top of the powder, and then put the other half of the embedding powder into the C / C composite material. Specimen coverage.
[0032] Put the above-mentioned graphite crucible into a hot-press vacuum r...
