TEMPERATURE ON CORROSION OF CERMETS ALLOY ABSTRACT Tungsten carbides (WC) are widely used as wear resistant components such as seal‚ valves‚ rings‚ nozzle and bearings. But in some processing operations‚ the environment necessarily includes severe corrosion or extremes of temperatures. In this research‚ commercially cobalt tungsten carbide (WC-6%Co) and nickel tungsten carbide (WC-9%Ni) was examined in seawater (3.5% salinity) to know the effect of temperature on corrosion for both of this
