Why Is Cemented Carbide So Hard? 54

?????????? Cemented carbide is mainly composed of tungsten carbide and cobalt. Tungsten carbide (WC) is a metal ceramic with a Vickers hardness of up to 2200 HV, close to the 10000 HV of diamond. Its crystal structure is hexagonal, and carbon atoms and tungsten atoms are bonded by strong covalent bonds with a bond energy of up to 700 kJ/mol, giving it extremely high hardness. Cobalt is used as a binder, and the content is usually 6%-15%. Through powder metallurgy,…

How Is the Wear Resistance of Cemented Carbide? 47

?????????? The wear resistance of cemented carbide comes from the high hardness of tungsten carbide, with a Vickers hardness of 2200 HV. The crystal structure is hexagonal, and the bond energy of carbon-tungsten covalent bonds is as high as 700 kJ/mol, which has strong wear resistance. Cobalt binder enhances the bonding force between particles and reduces wear and tear. Experiments show that after 1000 frictions, the wear amount of cemented carbide is only 1/10 of that of steel! Due to…

【Know Tungsten】Steel-Bonded Carbide Flow Disc 156

? The hard phase (tungsten carbide or titanium carbide) of steel-bonded carbide generally accounts for 30%-50% of the total mass of the alloy, and the rest is the steel matrix. Since the steel matrix accounts for a large proportion and the properties of steel are more obvious, it can be processed by forging and heat treatment. After powder mixing, pressing, sintering, forging, cutting, heat treatment and other processes, steel-bonded carbide products of various specifications and shapes can be obtained. Steel-bonded…
