Embodiment 1
[0014] Step 1: Polish the carbon / carbon composite material, ultrasonically clean it in absolute ethanol for 20 minutes, and dry it at 110°C;
[0015] Step 2: Weigh 65g Si powder, 25g C powder, 10g Al respectively 2 o 3 powder, placed in a ball mill jar, mixed and ball milled for 1 hour to make embedding powder; take half of the embedding powder and put it into a graphite crucible, put it into the carbon / carbon composite material treated in step 1, and then put Cover with the other half of the embedding powder, and add a graphite crucible cover; put the graphite crucible into a vertical vacuum furnace, and after vacuuming, raise the furnace temperature to 1900°C at a heating rate of 5°C / min, keep it warm for 3 hours, and turn off the power Natural cooling, the whole process is protected by argon gas, the flow rate of argon gas is 2L / min, and the carbon / carbon composite material with SiC inner coating is obtained;
[0016] Step 3: Put Yb 2 o 3 Powder and SiO 2 Powder press ...
Embodiment 2
[0020] Step 1: Polish the carbon / carbon composite material, ultrasonically clean it in absolute ethanol for 30 minutes, and then dry it at 120°C;
