Abstract

The invention provides a zirconium oxide-based ceramic tool material, which is prepared from the following raw materials in parts by weight: 50-60 parts of zirconium oxide, 30-35 parts of aluminium oxide, 1-2 parts of borax, 4-5 parts of barium carbonate, 1-2 parts of sodium humate, 2-4 parts of carboxymethylcellulose, 2-3 parts of carbonyl nickel powder, 3-5 parts of LiSbO3, 4-6 parts of potassium-sodium niobate, 2-3 parts of cerium oxide, 1-1.5 parts of lanthanum nitrate, a proper amount of deionized water, 1-1.4 parts of polyacrylic acid, 0.7-1.2 parts of polyethylene glycol, a proper amount of ethanediol and 3-4 parts of an anti-abrasion aid. Due to addition of carbonyl nickel powder to the ceramic, the thermal conductivity of the ceramic is increased, a tool is prevented from overheating, the ceramic has very high hardness and abrasive resistance, the ceramic tool is suitable for cutting and chipping a high-hardness material and is hardly aged or broken off; due to use of the anti-abrasion aid, the surface smoothness, abrasive resistance and heat resistance of the ceramic are improved.

Description

technical field [0001] The invention relates to the field of ceramic cutting tool materials, in particular to a zirconia-based ceramic tool material and a preparation method thereof. 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 purpose of the present invention is to provide a zirconia-based ceramic tool material and its preparation method. The cerami...
