Description
Technical Field
The invention belongs to the field of superhard material manufacturing, and particularly relates to a method for preparing a nano PCBN composite sheet by nano CBN powder at high temperature and high pressure.
Background
The main hard components of modern cutter materials, such as high-speed steel, hard alloy and ceramic, are carbide, nitride and oxide. The hardness of these compounds is up to 3000HV, plus the overall hardness of the cementitious substance is below 2000 HV. For the processing of modern engineering materials, the hardness of the tool material is not applied in some cases, and then the superhard tool material is produced. Superhard cutter materials are mainly Cubic Boron Nitride (CBN) and diamond, and their hardness is several times higher than other cutter materials. The hardness of diamond is highest, which can reach 10000HV, and the hardness of CBN (8000-9000 HV) is second to diamond. The diamond cutter is only suitable for processing nonferrous metal materials and nonmetallic materials, and the high temperature resistance of the diamond cutter is poor; the CBN cutting tool is chemically inert to ferrous metals (metals containing iron group elements), is resistant to high temperature, is particularly suitable for cutting ferrous metals, and is also suitable for machining common hard and brittle materials.
However, cubic boron nitride single crystal is difficult to be made into a large-sized tool, and has anisotropy of single crystal, which is influenced by crystal cleavage mechanism, and some mechanical properties of CBN, such as hardness and wear resistance, have strong directionality, thereby limiting its industrial application. In order to meet the requirement of industrial processing, the cubic boron nitride composite material composite sheet is developed. The material is prepared by sintering cubic boron nitride micropowder with or without binder at high temperature and high pressure. The cubic boron nitride composite material sintered at high temperature and high pressure can make up the defects of single crystals in some aspects, and the size of the composite sheet is larger, so that the cubic boron nitride composite material has a very wide development space in industry.
The size of the cubic boron nitride grains directly affects the sintering strength and the breakage resistance of the PCBN compact. The cubic boron nitride particles with fine crystal grains can increase the interface area and improve the sintering strength and the crack expansion resistance of the PCBN composite sheet, and the smaller the size of the cubic boron nitride crystal grains is, the stronger the breakage resistance of the PCBN composite sheet is, and the better the cutting sharpness of the PCBN composite sheet is. The small-grain cubic boron nitride crystal grains can provide larger reaction specific surface area, thereby inducing transformation and crystal epitaxial growth to obtain the PCBN compact with a completely compact microstructure. The density and hardness of the material can be obviously improved by using the nanoscale CBN particles to prepare the PCBN, and the application of the PCBN composite sheet is widened.
