Cemented Carbide - an overview | …

The trend of decreasing the WC mean grain size in WC-Co cemented carbides resulted in the development of cemented carbides with WC grain size close to the nanoregion (100 nm or less). Such cemented carbides with WC mean grain size of nearly 0.2 μm (200 nm) are designated in the literature as "near-nano cemented carbides" ( Brieseck, et al., 2009, pp. 239-246 ).

Abrasive blasting - Wikipedia

Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.A pressurised fluid, typically compressed air, or a centrifugal wheel is used to propel the blasting material (often …

Wear Properties of Nitride-Bonded Silicon Carbide under

19.04.2021· graphene (PNB) [3] or zirconium ceramics (ZrO2) [4], opens a considerable perspective for silicon carbide. The resistance to brittle cracking is a limitation of their resistance to tribological wear. Grain size distribution is also of great importance because resistance to tribological wear decreases with increasing grain size of the abraded
