High-entropy ceramic-transition metal combined tungsten carbide-based hard composite material and preparation method thereof

The invention relates to a high-entropy ceramic-transition metal combined tungsten carbide-based hard composite material and a preparation method thereof, and belongs to the technical field of preparation of new materials and hard composite materials. The high-entropy ceramic-transition metal combined tungsten carbide hard composite material is prepared by taking high-entropy ceramic-transition metal as a binding agent and tungsten carbide as a hard phase through sintering. According to the preparation method, cobalt (Co) can be introduced into a crystal structure of high-entropy ceramic (HECs), tungsten carbide (WC) and the HECs have good compatibility, therefore, the HECs are used as an intermediate medium, good interface diffusion is achieved between the HECs and Co and WC, the HECs and Co become good binding agents of the WC-based hard composite material, the sintering temperature is low, the sintering temperature is high, and the sintering time is long. The obtained sintered body is uniform and fine in s
