Tungsten carbide material for wedge bonding chopper and production method of tungsten carbide material
The invention discloses a tungsten carbide material for a wedge welding chopper. The tungsten carbide material comprises the following components in percentage by weight: 76-89.5% of WC, 5-10% of TiC, 2-8% of Co, 2-8% of Ni, 0.2-1% of Cr2C3, 0.2-1% of VC, 0.5-2.5% of Mo2C and 0.5-5.5% of K, k is at least one of a tantalum niobium carbide or tungsten titanium carbide solid solution and carbides of tantalum, hafnium, niobium, rhenium or zirconium; the preparation method comprises the following steps: 1, preparing the components according to the designed components; 2, sequentially carrying out wet mixing and ball milling on the prepared components, drying and screening; 3, mixing the standby powder and a forming agent in proportion; 4, the standby mixture is subjected to die pressing to form a tungsten carbide wedge welding chopper pressed blank; and 5, degreasing and sintering the pressed blank formed by die pressing. According to the method, the wear resistance during bonding of the leads of different materials is improved, the method is suitable for bonding of the leads of different sizes, the application range of the lead materials of the tungsten carbide material is further widened, the applicability of the tungsten carbide material in fine wire and thick wire wedge bonding chopper is improved, the production efficiency is improved, and the production cost is reduced.
