摘    要:在硅酸钠-氢氧化钠电解液中以Na5P3O10作为稳定剂,通过改变Ce(NO3)3/Ce2(SO4)3的含量对Ti6Al4V合金进行微弧氧化,用XRD、SEM、EDS对试样表面所获得的氧化膜进行表征,并研究电解液中不同Ce(NO3)3/Ce2(SO4)3含量对氧化膜表面形貌的影响.结果表明,随着电解液中Ce3+的加入量增加到0.3 g/L,氧化膜表面的致密性减小,在此基础上加入0.5 g/L的Na5P3O10时,氧化膜致密性增加.EDS分析结果显示,膜层含有Ti、Na、Al、Si、P、O及Ce等元素;XRD分析结果表明,氧化膜的相组成为Ti、锐钛矿以及金红石.

关 键 词:Ti6Al4V  Ce  微弧氧化  电解液  陶瓷层

Abstract:Ceramic coatings were obtained by micro-arc oxidation on the surface of Ti6Al4V alloy in sodium silicate and sodium hydroxide electrolyte under different content of Ce(NO3)3/Ce2(SO4)3.The effects of Ce(NO3)3/Ce2(SO4)3 contents of in electrolyte on the characteristics of MAO coating were investigated.The thickness of the coatings was measured.The surface morphology of the coatings was observed by SEM and phase compositions were analyzed by XRD.The results reveal that the compactness of the coating decreases ...
Keywords:Ti6Al4V  Ce  micro-arc oxidation  electrolyte  ceramic coating
