中文摘要:
      为了研究交流脉冲占空比和频率对微弧氧化膜的影响。采用恒电流方式对TC4钛合金进行微弧氧化,用扫描电镜和X衍射仪分析膜层的表面形貌及相结构。结果表明:随占空比的增大,微弧氧化膜层的生长速率增大,金红石相Ti01相对含量增加;随频率的增大,微弧氧化膜层的生长速率减小,表面趋于平整,锐钛矿相和金红石相Ti0.相对含量与处理频率无关。
英文摘要:
      In order to reveal the effect of altemate pulse duty cycle and frequency on micro-arc oxidation coatings, ceramic coatings were formed using alternate pulse micro-arc oxidation method on alloy Ti6A14V and a constant current regime of micro-arc oxidation was applied. SEM and XRD were employed to analyze surface morphology and the phase of the coatings. The results show that with the increasing of duty cycle, the growth rates of the MAO coatings increase and the relative contents of rutile Ti02 increase. With the increasing of frequency, the growth rates of the MAO coatings decrease and the roughness of the coating surface decreases gradually. The relative content of rutile and anatase Ti02 keeps invariable with the variation of the frequency.
