Example Embodiment
[0015] Example 1: Refer to Figure 1 and Figure 2, take a 3D woven C fiber woven body, cut it into a Φ(70-100)×65mm ring sample, weigh it, and put it in a chemical vapor deposition furnace; Below 50Pa, heat to 1100°C, first deposit CVD-C, and pass Ar and C in a ratio of 3:1 3 H 6 Carry out CVD-C deposition, keep the furnace pressure at 1000~2000Pa and deposit for 20hr; then carry out TaC-SiC co-deposition, using Ar as carrier gas to remove TaCl 5 Introduce into the furnace and add C at the same time 3 H 6 And reducing gas H 2 , Use H 2 As carrier gas, CH 3 SiCl 3 (MTS) is brought into the deposition furnace by another pipeline, Ar is used as dilution gas, H 2 The ratio with Ar is 1:(1~5), H 2 : MTS≥10, keep the furnace pressure 500~1000Pa for 60hrs; stop the deposition; continue to pass Ar for 30min, vacuum and cool down; when it reaches room temperature, open the furnace for sampling, weighing and testing. The car removes the carbide skin on the inner and outer surface layers of t...
Example Embodiment
[0018] Example 2: With reference to Figure 1, take a 4D woven SiC fiber woven body, cut it into a Φ(70-100)×65mm ring sample, weigh it, and put it in a chemical vapor deposition furnace; vacuum it to below 50Pa, Warm up to 1300°C for TaC-HfC co-deposition, and use Ar as carrier gas to remove TaCl 5 Introduce into the furnace while adding CH 4 And reducing gas H 2 , Using Ar as carrier gas to HfCl 4 Introduce the deposition furnace from another way, and add CH at the same time 4 And reducing gas H 2 , Ar is used as the diluent gas, keep the furnace pressure 500~1000Pa for deposition 60hr; stop the deposition; continue to pass Ar for 30min, vacuum and cool down; when it reaches room temperature, open the furnace for sampling, weighing and testing. The car removes the carbide skin on the inner and outer surface layers of the diameter, ultrasonically cleans and dries, and puts it in a deposition furnace to continue deposition, repeating TaC-HfC co-deposition many times. Then a dense S...
Example Embodiment
[0019] Example 3: Referring to Figure 1, take a 4D woven boron B fiber (or tungsten W wire) woven body, cut into a Φ(70-100)×65mm ring sample, weigh it, and put it in a chemical vapor deposition furnace ; Other processes are the same as in Example 2, and a densely structured B fiber (or tungsten W wire) reinforced TaC-HfC co-deposition composite material can be obtained.
