Abstract
A corrosion resistant cermet comprises a ceramic component (e.g., WC) and a binder alloy 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, osmium, iridium, and platinum). Plungers for hyper compressors used in the corrosive environments generated during the manufacture of low density polyethylene (LDPE) or ethylene copolymers are an example of the use of the corrosion resistant cermet.
