Few materials have had a greater impact on our economy and industrialized culture than cemented tungsten carbide. Hard and wear-resistant, this material is used for products as interesting and varied as ballpoint pen balls, fishing rod guide rings, wear parts, dental drill bits, armor-piercing shell cores and, most significantly, cutting tools.
CVD = Chemical Vapor Deposition , the deposition of hard-material layers in a chemical gas-phase process. At temperatures of approx. 1000°C, the gaseous-layer components surround the tool and react with elements from the tool surface to form a layer with a very high level of adhesion!
