    摘要:

    利用微弧氧化技术在锆材表面原位生成微弧氧化膜层。研究电压、占空比、频率和电流密度对锆材微弧氧化膜层厚度的影响,并利用单因素方差分析法,分析各电参数对膜厚影响的显著性。结果表明:在试验范围内,随着电压的升高、占空比的增大、频率的减小或电流密度的增大,锆材微弧氧化膜层厚度增加;各电参数对微弧氧化膜层厚度影响的主次顺序为:电压和电流密度>占空比>频率,其中频率对膜层厚度无明显影响。

    Abstract:

    A coating was prepared on zirconium by micro-arc oxidation. The effects of voltage, frequency, duty-cycle and current density on the thickness of the MAO coating were studied, and the significances of the effects were also studied by ANOVA. The results show that the thickness of the coating increases with the voltage, duty-cycle and current density increasing and the frequency decreasing separately, the primary-secondary order of the effect significances for all parameters is voltage and current density > duty-cycle > frequency, and the frequency has little effect on the coating thickness.
