2020/5/30· Both boron carbide and silicon carbide are non-oxide engineering ceramics. There are 19 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown. For each property being compared, the top bar is
Tungsten carbide is approximately twice as stiff as steel, with a Young''s modulus of approximately 530–700 GPa (77,000 to 102,000 ksi), and is double the density of steel—nearly midway between that of lead and gold.It is comparable with corundum (α-Al2 O 3) in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond powder
2019/1/2· The hardness of hybrid composites has been increased due to incorporation of stiffer and stronger reinforcement in Fenghong, C., Chang, C., Zhenyu, W. et al. Effects of Silicon Carbide and Tungsten Carbide in Aluminium Metal MatrixSilicon 11, 2625–2632
The fully amorphous silicon carbide has a hardness value that is about 40% of the unimplanted value. The elastic modulus of the implanted material is lower for all implanted conditions.The hardness and elastic modulus of α-SiC single crystals were determined using an ultra-low load micro-indentation hardness tester for implantation conditions that produced both crystalline and
2019/8/27· Carbide-reinforced martensitic steels, known as high-speed steels (HSSs), have been used as tool materials in various industries because of their high hardness and wear resistance. Nonetheless

The hardness of Si-doped boron carbide at 500 mN (~50 GPa) is comparable to that of the undoped counterpart (for details, see fig. S3A). Compared with the undoped boron carbide, the Si-doped boron carbide has become slightly softer, which was shown in typical nanoindentation load-displacement curves for undoped and Si-doped boron carbides (fig. S3B).

Chromium(II) carbide is a ceramic compound that exists in several chemical compositions: Cr 3 C 2, Cr 7 C 3,and Cr 23 C 6.At standard conditions it exists as a gray solid. It is extremely hard and corrosion resistant. It is also a refractory compound, which means that …
2. Is silicon carbide naturally abrasive? Since its initial discovery in 1891, SiC has been produced in powder form and used as a synthetic abrasive material.This is due to its high level of hardness, ranking 9 on the Mohs scale, which outclasses most known materials, only to be surpassed by a handful of others, such as boron, boron nitride, and diamond.
