Abstract
The invention relates to a method for manufacturing hard alloy materials, which comprises the following steps: 1. taking the following raw material substances in percentage by weight: 10 to 20 percent of composite hard phase tungsten carbide powder in a particle form of 10 to 15 microns, 20 to 30 percent of composite hard phase tungsten carbide powder in a particle form of 5 to 10 microns, 20 to 30 percent of composite hard phase tungsten carbide powder in a particle form of 1.0 to 1.5 microns, 1.5 to 2 percent of chromium carbide powder and 25 to 30 percent of cobalt powder; and 2. mixing the raw material substances according to the mixture ratio, grinding, pressing and forming the materials, then, carrying out heat insulation for 30 minutes under the condition between 1500 DEG C and 1600 DEG C, and obtaining the hard alloy materials. The method provided by the invention is simple and reliable, and the produced hard alloy materials belong to the hard alloy materials with the advantages of wear resistance, impact resistance, stable quality and bicrystal corrosion resistance.
Description
Technical field
The present invention relates to a kind of manufacture method of Hardmetal materials.
Background technology
At present, the main trade mark of Wimet sheet material is YG15, YG20 etc., such trade mark in process of production, all adopt the WC powder production of single specification, the shortcoming of single powder is doublely to make this material possess the characteristics of high strength and high hardness simultaneously, promptly can not make product possess wear-resisting impact-resistant again characteristics simultaneously; And bonding component only is a kind of element of cobalt, but the oxidation-resistance of cobalt and corrosion resistance are relatively poor, causes occurring easily in online cutting of sheet material and the electrospark machining defectives such as corrosion and crackle; Simultaneously, at high temperature, WC grain is dissolved in the liquid phase cobalt, causes WC grain to be grown up unusually easily.Along with the expansion of Wimet sheet material use range, with and in various environmental applications, traditional Wimet can not adapt to Working environment complicated and changeable day by day.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method who possesses wear-resisting shock-resistant again and stay-in-grade double crystal corrosion resistant cemented carbide material simultaneously.
Content of the present invention is, it comprises the steps,
(1), gets following raw materials by weight percent material, the composite ganoine phase tungsten carbide powder 10-20% of 10-15 micron particle, the composite ganoine phase tungsten carbide powder 20-30% of 5-10 micron particle, the composite ganoine phase tungsten carbide powder 20-30% of 1.0-1.5 micron particle, carbonization chromium powder 1.5-2%, cobalt powder 25-30%;
(2) described raw material is mixed by proportioning, grind, compression moulding is incubated 30 minutes then under 1500-1600 ℃ of condition, get described Hardmetal materials.
The invention has the beneficial effects as follows that by adjusting the crystal grain collocation of wolfram varbide, make the ratio of the wolfram varbide of different size reach best arranging effect, this arranging effect is different because the granular size of original WC and ratio are different.In the present invention, adopt the wolfram varbide collocation of three kinds of variable grain granularities, and grow up unusually, simultaneously by tungsten carbide crystal grain in the adding carbonization chromium powder inhibition of sintering knot process, the chromium carbide powder that adds is uniformly distributed in the alloy material, can make this material possess corrosion resistant characteristics.
In sum, adopt the Hardmetal materials of the present invention's preparation to possess wear-resisting shock-resistant again and steady quality, simple and reliable, the low cost of manufacture of the present invention simultaneously.
