【 摘 要 】

Ni-Co-SiC composite coatings were prepared on 45 carbon steel by electrodeposition for high temperature anti-oxidation. The high-temperature oxidation was studied by circulating oxidation test. The prepared composite coating shows continuous Ni-Co matrix and uniformly dispersed SiC particles, and there are no cracks and pores and other flaws in the composite coating. The results also reveal that due to the reactive-phase effect of the embedded SiC particles, the oxidation rate of the substrate decreases largely at high temperature. The Ni-Co-SiC composite coating exhibits better high-temperature oxidation compared with Ni-Co coating and 45 carbon steel.
