摘要
An energy-saving and high-efficient powder Al and Si codeposition process was employed on 1045 steel, the new technology was mainly based on applying direct current field (DCF) with proper parameters between the treated samples and the powder. The microstructure, thickness and the phase constituents of the coating were analyzed by OM and XRD. The high temperature oxidation resistance for a total duration of 120h and the corrosion resistance in 10% H2SO4 for 8h were investigated. The results showed that DCF could lower heating temperature and accelerate the diffusion rate. The phase of the coatings with DCF was composed of Al0.7Fe3SiO3 and AlFe3. The treated samples had good high temperature oxidation resistance and corrosion resistance in 10% H2SO4 solution.
