Abstract

The invention discloses a high-strength and high-toughness ceramic composite material and an application thereof to manufacturing of a cutter. The ceramic composite material is prepared from the following raw materials in parts by weight: 55 to 65 parts of zirconia, 20 to 30 parts of alumina, 6 to 8 parts of ceria, 4 to 6 parts of lanthana, 3 to 5 parts of borax, 1 to 3 parts of borazon, 2 to 4 parts of zinc dialkyl dithiophosphate, 0.6 to 0.8 part of sodium alginate, 0.4 to 0.6 part of sodium lignin sulfonate, 0.8 to 1.2 parts of sodium hexametaphosphate, 1 to 3 parts of polyethylene glycol and 7 to 9 parts of deionized water. The ceramic composite material provided by the invention has high hardness and wear resistance, is suitable for preparing the ceramic cutter and is difficult to age and break when being used for cutting high-hardness materials; the preparation process of the ceramic composite material is simple and feasible.

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a high-strength and high-toughness ceramic composite material and its application in manufacturing cutting tools. Background technique [0002] Ceramic cutting tools have the characteristics of high hardness, high density, high temperature resistance, anti-magnetization, anti-oxidation, strong corrosion resistance, good chemical stability, and high wear resistance. They are good substitutes for traditional cutting tools such as high-speed steel. The problem of scarcity of resources such as molybdenum and nickel has been solved. However, the current ceramic cutting materials still have problems such as high cost, insufficient toughness, high brittleness, uneven hardness, poor heat dissipation, and poor self-lubrication, which need to be solved. Contents of the invention [0003] The first object of the present invention is to provide a high-strength and high-toughness ceramic c...
