A cermet comprises a ceramic component (e.g., WC) and a binder comprised of a major component (e.g., one or more of iron, nickel, cobalt, their mixtures, and their alloys) and at least one additive component (e.g., one or more of ruthenium, rhodium, palladium, osnium, iridium, and platinum) which imparts corrosion resistance to the cermet. Parts composed of this cermet include plungers for hyper compressors used in the corrosive environments generated during the manufacture of low density polyethylene (LDPE) or ethylene copolymers. |
