摘 要:在添加乙酸铜、乙酸镁的磷酸-氟锆酸钾电解液中对纯钛TA2基体进行微弧氧化处理,制备出颜色均匀的浅棕色陶瓷膜层。通过X射线衍射分析(XRD)、扫描电子显微分析(SEM)及附带的能谱(EDS),研究了陶瓷膜的表面和截面形貌、元素分布、相组成;用分光光度计测量了膜层的颜色,根据热震试验和三点弯曲法评价了膜层与基体的结合强度。结果表明:随着微弧氧化时间的延长,膜层中铜镁元素的含量增加,膜层的颜色随之发生变化,膜层与基体的结合强度降低。热震实验结果表明,膜层与基体有较高的结合强度。A light brown ceramic coating was obtained on TA2 pure titanium substrate by microarc oxidation in the H_3PO_4-K_2ZrF_6 electrolyte system containing Cu(CH_3COO)_2 and Mg(CH_3COO)_2. The XRD,SEM,EDS methods were employed to investigate the phase constitutes,element compositions and morphologies of the coatings.The color of coatings were tested by spectrophotometer,the adhesion strength of the coatings to substrate were investigated by thermal impact and three-point bending method. The results show that with increasing oxidation time,the content of copper and magnesium element were added and the color of the coatings changed too,and bonding strength was reduced.After thermal shock the coating and the substrate remains a high bonging strength.
