摘要

Mn-Co and Cu-Mn based alloy coatings are deposited on 430 SS by high energy micro-arc alloying process, and then alloy coatings are oxidized at 750 °C in air to form the spinel oxides. Some composite oxides, such as Co₃O₄, Mn₂O₃ and (Mn,Co)₃O₄, are formed at the initial stage of oxidation. The single-phase spinel (pure MnCo₂O₄) without impurity phases is only found on the surface of Co-33Mn-17Cu oxide layer with the extended oxidation time, its area-specific resistance values at 500 °C to 800 °C are low and close to that of Mn-35Cu oxide layer which mainly composed of Cu_1.2Mn_1.8O₄ spinel.
