The invention discloses a strong bonding anti-ablative high-entropy ceramic coating and a preparation method thereof. TiC, ZrC, HfC and TaC are mixed, and the high-entropy ceramic coating is prepared by ball milling, pressing and sintering. The TiC, ZrC, HfC and TaC have extremely high melting point and thermal stability, and a good phase between TiC, ZrC, HfC and TaC is obtained Capacitive. In particular, the high entropy ceramic coating prepared by discharge plasma sintering has a short period, and the binding force between the high entropy ceramic coating and the carbon matrix is very strong, which is expected to completely solve the problems such as interface compatibility and large difference in thermal expansion coefficient.
