Abstract
The present invention discloses a ternary boride metal ceramic preparation process. The technical scheme comprises that: the ternary boride metal ceramic comprises a ternary boride (Mo2FeB2, Mo2NiB2, WCoB and the like) and a binding phase containing Cr, Ni, Mo, Fe and other metals, wherein boride alloy powder and a metal matrix are subjected to in situ reaction liquid phase sintering to obtain the ternary boride, and the components of the ternary boride metal ceramic comprise 7-8% of B, 40-50% of Mo, 10% of Cr, 10% of Ni, 0.8% of C, and the balance of Fe. The preparation process of the present invention has the following characteristics that: the shape of the binding phase of the ternary boride can be changed by controlling the addition amount of Cr, Ni and Mo so as to obtain the desired mechanical property of the material.
Description
Technical field
The invention discloses a kind of preparation technology of ternary boride cement.
Background technology
Boride ceramics is gap phase compound, can form the covalent linkage of Various Complex between B and B, and meanwhile, boron can form ionic linkage with many atoms metals again.M-M metallic bond, B-B covalent linkage and B-M ionic linkage is comprised in major part boride.These features of boride determine it and have high-melting-point, high rigidity, high-wearing feature and improved corrosion performance, are therefore widely used in the mechanical component of Hardmetal materials, high-abrasive material, corrosion resistant material and wear-and corrosion-resistant.In borides, TiB
2, ZrB
2and CrB
2the boride ceramics that is hopeful most to be used widely is considered to because of its excellent performance still, due to TiB Deng binary borides
2easily there is strong chemical reaction on binary borides pottery and metallic matrix, thus sintering character is worsened.Through studying for many years, its degree of being practical is improving constantly, but compared with common carbide base cemented carbide, intensity and the Fracture Toughness of this kind of mechanically resistant material are low, also there is a lot of problem as structured material.Therefore, the development of new that needs boride series hard metal.
In order to overcome the problems referred to above, the present invention by make use of binary borides easily with the characteristic of metal reaction, formed in sintering process and ternary boride that metallic matrix coexists and the binary borides that consumes in raw material.Ternary boride cement of the present invention is by ternary boride (Mo
