Precision forming and casting method of high-volume-fraction titanium-based composite material

The invention aims to provide a precision forming and casting method of a high-volume-fraction titanium-based composite material, which specifically comprises the steps of preparing a titanium-based composite material electrode for a vacuum consumable electrode arc skull furnace, and then processing a required graphite casting mold; preparing a plasma spraying powder raw material, and then spraying a refractory coating on the surface of the graphite casting mold by utilizing a plasma spraying technology; after vacuum degassing of the graphite casting mold, assembling and combining according tocasting mold assembling requirements; and placing the combined casting mold in a vacuum consumable skull smelting furnace for vacuum centrifugal casting. The titanium-based composite material castingcast by using the process provided by the invention has the advantages of high internal quality, high surface quality, high dimensional precision, high performance and impact resistance. Meanwhile, compared with other process
