What Are the Right Abrasives for Your Metal Removal …
Silicon Carbide Silicon carbide crystals are hard, thin and very sharp—in fact, the only materials harder than silicon carbide are diamond and cubic boron nitride. Unfortunately, silicon carbide’s hardness and shape make it brittle, so even though it cuts quickly, it also tends to break down a bit faster than other abrasives, especially under extreme forces.

Cutting tool materials - Coromant
The first CVD coated cemented carbide was the single layer titanium carbide coating (TiC). Alumina coatings (Al2O3) and titanium nitride (TiN) coatings were introduced later. More recently, the modern titanium carbonitride coatings (MT-Ti(C,N) or MT-TiCN, also called MT-CVD) were developed to improve grade properties through their ability to keep the cemented carbide interface intact.

Cutting benefits of ceramic and cermet tools - Cutting …
21/7/2018· Cermet is more brittle than tungsten carbide, so cermet cutting tools are susceptible to chipping and breaking when stressed while taking heavy cuts, he said. As a result, more users consider cermet tools suitable for finishing only at a 0.010" to 0.020" DOC.
Analysis of The Etching Mechanisms of Tungsten in Fluorine …
or CF4. Extra tests using SF 6 + 02 show results similar to the ones reported in Ref. 5-7. For oxygen flows of over 25% of the total flow, the silicon etch rate starts to decrease, as expected. The tungsten etch rate starts to decrease at 50
