摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a submicron cemented carbide cutting tool insert consisting of tungsten carbide and cobalt by the conventional process comprising a stage of subjecting a powder mixture of WC, Co, and a conventional grain growth inhibitor to wet-kneading to form a slurry, a stage of drying the slurry into powder, a stage of subjecting the powder to uniaxial pressing in a pressing tool to form an article of desired shape, and finally a stage of sintering. SOLUTION: At the time of the sintering stage, a cemented carbide insert of this kind tends to shrink usually in a direction parallel to the pressing direction rather than in a direction perpendicular to the pressing direction. As the result, the pressing requires a special tool or requires, after sintering of the insert, long-time grinding which causes a raise in manufacturing costs. In this method, with respect to a cemented carbide of 7.5 to 25 wt.% Co content, such defect can be removed by using a WC powder having an FSSS grain size dWC of less than 1 μm and a Co powder having an FSSS grain size dCo satisfying the condition that the value of dWC/dCo becomes 0.75-1.5.

摘要： PROBLEM TO BE SOLVED: To provide a cutting tool insert including cemented carbide base material and a coated film. SOLUTION: The cemented carbide base material includes 73-93 wt.% WC, 4-12 wt.% binder phase, and cubic carbide phase, and substantially has a surface area free from cubic carbide phase and rich in binder phase. The cubic carbide phase includes elements from 1Vb and Vb groups of the periodic system, and has the tantalum content of the level corresponding to industrial impurities. This insert demonstrates favorable blade strength and thermal shock resistance. COPYRIGHT: (C)2003,JPO

摘要： A fine grained cemented carbide powder mixture for cutting tool inserts for metal machining includes WC-powder with a Scott density of 2.75-3.75 g/cm3 and a compacting density after dry pressing at 100 MPa within 8.8-9.8 g/cm3. The sintering shrinkage of the fine grained cemented carbide powder mixture is 16.8 to 17.9% at a compacting pressure of 150 MPa. A method of making the powder mixture is also described.
