Abstract
The invention discloses a hard alloy material, which comprises, by weight, 80-90 parts of a hard phase, 2-20 parts of a binding phase, and 1-10 parts of additives, wherein the hard phase comprises (calculated as the weight of the hard alloy material) 60-88 parts of WC and 1-20 parts of SiAlCN, the binding phase comprises Co and Ni, and the additives comprise one or a mixture comprising more than two selected from W, Cr, V, Mo, Ta, Nb, Ti, C and rare earth elements. The prepared hard alloy material of the present invention has characteristics of high strength and high anti-oxidation property, and can improve the high temperature strength, the hardness and the toughness of the hard alloy tool.
Description
Technical field
The present invention relates to hard alloy technical field, specifically a kind of Hardmetal materials.
Background technology
Hard alloy is known as " tooth of industry ", is a kind of efficient tool material and structural material, is mainly used in numerical control
Lathe Precision Machining cutting-tool engineering field, it may also be used for the engineering machinery wear-proof technique fields such as mould and rock drilling, mine, building,
Industrial development and scientific and technological progress are served important impetus.
Conventional rigid alloy is as Binder Phase, with WC as hard phase with Co, Ni, Fe simple substance element.Along with using temperature
The rising of degree, particularly more than 400 DEG C, Co, Ni, Fe simple substance element is Binder Phase and WC hard phase starts oxygen
Changing, WC oxidation generates WO3, Co oxidation and generates CoWO4, and oxide is loose porous, does not have protectiveness, causes conventional rigid
The performances such as alloy bending strength, hardness significantly reduce, and high temperature life is significantly reduced.
Summary of the invention
The technical problem to be solved in the present invention is to provide the Hardmetal materials that a kind of intensity is high, have antioxygenic property.
In order to solve above-mentioned technical problem, the present invention takes techniques below scheme:
A kind of Hardmetal materials, including hard phase 80-90 part, Binder Phase 2-20 part and the additive 1-10 of parts by weight meter
Part, hard phase is made up of WC and SiAlCN, and it is 60～88 parts that WC accounts for the parts by weight of described Hardmetal materials,
It is 1-20 part that SiAlCN accounts for the parts by weight of described Hardmetal materials, and Binder Phase is made up of Co and Ni, additive include W,
One or more mixing in Cr, V, Mo, Ta, Nb, Ti, C and rare earth element.
The granularity of described WC is 0.05～1.5 μm, and the granularity of SiAlCN is 0.01～1 μm, and the granularity of Co is 5
～10 μm, the granularity of Ni is 2～8 μm.
The particle mean size of described WC is less than 1.2 μm.
The weight ratio of Co and Ni in described Binder Phase is 1:0.05～1:1.
Described hard phase is 85 parts, and Binder Phase is 10 parts, and additive is 5 parts.
Described hard phase is 90 parts, and Binder Phase is 8 parts, and additive is 2 parts.
The present invention is by adding the SiAlCN of Precise levels in hard phase, thus is used for after mixing homogeneously with Binder Phase
Make sintered-carbide tool, it is possible to make hard phase have higher hardness and antioxygenic property, it is possible to increase prepared hard closes
Metal working tool elevated temperature strength, hardness and toughness.
