Title: METHOD FOR FABRICATING LOW-COST, HIGHLY WEAR-RESISTANT CERAMIC-ALLOY COMPOSITE LINER
Abstract:
Provided is a method for fabricating a low-cost, highly wear-resistant ceramic-alloy composite liner; preprocessed ceramic particles are uniformly mixed with a low-melting-point alloy powder using a binder to obtain a mixture; a mold cavity is filled with the mixture for forming; a blank and the mold are placed together into a drying chamber to dry, and are sintered in a vacuum furnace to obtain a ceramic prefabricated piece; the ceramic prefabricated piece is fixed to the surface of the casting cavity of the ceramic alloy prefabricated piece; then a wear-resistant alloy metallic liquid is poured to obtain a ceramic alloy prefabricated piece; the ceramic alloy prefabricated piece is subjected to thermally treated; a body of metallic material is smelted to form a metallic liquid, which is then poured into the casting cavity to obtain a liner base; lastly, the ceramic alloy prefabricated piece is welded to the liner base.
