How is cemented carbide made by sintering?
Cemented carbide is a metal material made by powder metallurgy with carbides and binder metals of one or more refractory metals.
Tungsten Carbide Cutting Heads High hardness (86～93HRA, equivalent to 69～81HRC);
Good thermal hardness (up to 900～1000℃, keeping 60HRC);
Good abrasion resistance.
The cutting speed of cemented carbide tools is 4 to 7 times higher than that of high-speed steel, and the tool life is 5 to 80 times higher. Manufacturing molds and measuring tools has a life span of 20 to 150 times longer than that of alloy tool steel. It can cut hard materials of about 50HRC.
However, cemented carbide is brittle and cannot be cut, and it is difficult to make integral tools with complex shapes. Therefore, inserts of different shapes are often made and installed on the cutter body or mold body by welding, bonding, mechanical clamping, etc. .
In 1923, Schroeter of Germany added 10% to 20% of cobalt to tungsten carbide powder as a binder, and invented a new alloy of tungsten carbide and cobalt. The hardness is second only to diamond, which is artificially made in the world. The first cemented carbide. When cutting steel with a tool made of this alloy, the cutting edge will wear out quickly, and even the cutting edge may crack. In 1929, Schwarzkov of the United States added a certain amount of compound carbide of tungsten carbide and titanium carbide to the original composition to improve the performance of the tool in cutting steel. This is another achievement in the development history of cemented carbide.
Cemented carbide can also be used to make rock drilling tools, mining tools, drilling tools, measuring tools, wear-resistant parts, metal abrasive tools, cylinder linings, precision bearings, nozzles, metal molds (such as wire drawing molds, bolt molds, nut molds, and Various fastener molds, the excellent performance of cemented carbide gradually replaced the previous steel molds).
In the past two decades, coated cemented carbide has also come out. In 1969, Sweden successfully developed a titanium carbide coated tool. The matrix of the tool is tungsten-titanium-cobalt cemented carbide or tungsten-cobalt cemented carbide. The thickness of the surface titanium carbide coating is only a few microns, but compared with the alloy tools of the same brand, The service life is extended by 3 times, and the cutting speed is increased by 25% to 50%. The fourth generation of coated tools appeared in the 1970s, which can be used to cut difficult-to-machine materials.
