Grinding of tool steel - Bohler Uddeholm

2017-8-22 · Grinding of Tool Steel 4 2. Silicon carbide is an abrasive that is used pri-marily for grinding cast iron and austenitic stain-less steels, although it can also be used for hard-ened tool steels. It occurs in two main variants: the black silicon carbide and a somewhat harder green variant, which is more brittle than the black material. 3.

SEALING SENSE

2007-1-24 · Silicon carbide can be used either as a rotating or sta-tionary face depending upon the seal design, manufacturer, and the other mating face material. Like other mechanical seal materials and designs, silicon carbide has distinct advantages as well as some disadvantages. Silicon carbide is very hard and has excellent abrasion and wear resistance.

Grain types — Klingspor

Subsumed in the egory of natural grain types are, in particular, flint, garnet and emery; however, these grain types are barely used any more in the production of abrasives. Instead, the abrasives produced today are usually made with synthetic grain types such as aluminium oxide, zirconia alumina, silicon carbide and ceramic aluminium oxide.

Ceramography - Wikipedia

2019-4-7 · Ceramography is the art and science of preparation, examination and evaluation of ceramic microstructures. Ceramography can be thought of as the metallography of ceramics. The microstructure is the structure level of approximately 0.1 to 100 µm, between the minimum wavelength of visible light and the resolution limit of the naked eye.

Microalloying Boron Carbide with Silicon to Achieve

Boron carbide (B 4 C) is a hard material whose value for extended engineering appliions such as body armor; is limited by its brittleness under impact. To improve the ductility while retaining hardness, we used density functional theory to examine modifying B 4 C ductility through microalloying. We found that replacing the CBC chain in B 4 C with Si–Si, denoted as (B 11 C p)–Si 2
