he iron-bed alloy with high contents of chronium, nickle and molybdenum under certain conditions could generate intermetallics distributed homogeneously in the alloy and result in composites which are resistant to wear and corrosion as well. The corrosion resistance of the composites in a solution simulated to that in phosphoric acid process was evaluated with electrochemical polarization measurements. With the increasing volume fraction of intermetallics, the passivity of the composite materials degrades slightly. As a whole, however, the composites under study with various amount of intermetallics exhibit excellent corrosion resistance.
