High-density Tungsten Carbide (WC) sputtering targets for DC/RF magnetron deposition of ultra-hard, wear-resistant thin films on cutting tools, dies, and precision components. WC coatings exhibit hardness of 22–30 GPa, a low coefficient of friction (~0.1–0.2), and exceptional thermal stability up to 900°C in inert atmosphere. CY Scientific WC targets are produced by hot-press sintering to > 96% theoretical density for splash-free, stable sputtering performance.
