Cobalt/Tungsten carbide(Co/WC ) composite powders consist of a tungsten carbide core coated with
a thin layer of cobalt. It's welcomed by the aviation, machinery, oil
departments.
Co/WC composite powders are superior to Co/WC hard alloy powders
for plasma spraying and detonation gun coating processes. The coating is of
good wear resistance at 500℃ and below, with a non-corrosive environment. It's widely used in aviation, machinery, oil, spinning
areas and etc.
