Metal toughened ceramic-based composite material for 3D printing
The invention provides a metal toughened ceramic-based composite material for 3D printing. Metal fibers are roundly embedded on the surface of ceramic microspheres to form metal toughened ceramic composite microspheres. The composite material is prepared from the following raw materials in parts by weight: 80 to 90 parts of ceramic microsphere, 5 to 10 parts of metal fiber, 1 to 1.5 parts of interface modifier, 0.1 to 0.5 part of activator, and 3 to 5 parts of bonding agent. The ceramic microsphere surface is modified through interface corrosion so as to form an embeddable interface on the surface of ceramic microspheres; then metal fibers are rolled and pressed by a disc grinder so as to embed the metal fibers into the surface of ceramic microspheres with eroded interface, thus metal toughened ceramic composite microspheres can be obtained, the metal fibers are winded and embedded on the surface of ceramic microspheres; the ball shape of the composite material meets the requirements of 3D printing, moreover, the metal fibers are arranged on the surface of ceramic microspheres in a net shape, thus after 3D printing and sintering, the metal on the ceramic product is arranged in a net shape, and the toughening is achieved.
