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。
Micro-arc Oxidation Technology is used to generate micro-arc oxidation film in situ on the surface of zirconium. The effects of voltage, duty cycle, frequency and current density on the micro-arc oxidation of zirconium oxide coatings were investigated. The single factor analysis of variance was used to analyze the significance of each parameter. The results show that the thickness of the MAO coatings increases with the increase of voltage, the increase of the duty cycle, the decrease of the frequency or the increase of the current density in the experimental range. The micro-arc oxidation The primary and secondary order of influence of film thickness is: voltage and current density> duty cycle> frequency, of which frequency has no significant effect on film thickness.
