Abstract

The invention discloses a low-cost ceramic cutting tool material prepared from the following raw materials in parts by weight: 0.6-0.7 part of water reducer, 2.6-3 parts of magnesium oxide, 2-3 parts of boron oxide, 10-15 parts of waste quartz crucible powder, 75-80 parts of alpha-Al2O3, 6-8 parts of SiC, 3-4 parts of WC, 2-3 parts of CaF2, an appropriate amount of deionized water, 1-1.4 parts of polyacrylic acid, 0.7-1.2 parts of polyethylene glycol, an appropriate amount of ethylene glycol and 3-4 parts of a wear-resistant aid. According to the preparation method disclosed by the invention, the waste quartz crucible powder is added into ceramic, so that the cost is reduced, the heat resistance of the ceramic is improved, the lubricating property of the ceramic is increased by adding CaF2, and the ceramic has high anti-friction property and wear resistance, can be used for manufacturing cutting tools and anti-friction wear-resistant structures, is low in cost and long in service life; and by using the wear-resistant aid provided by the invention, the surface smoothness, wear resistance and heat resistance of the ceramic can be increased.

Description

technical field [0001] The invention relates to the field of ceramic cutting tool materials, in particular to a low-cost ceramic cutting 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 low-cost ceramic cutting tool material and its preparation method. The ce...
