| 摘 要： | 针对微弧氧化法生成四方相BaTiO3薄膜的工艺参数影响规律进行研究.将Ti板置于含Ba2+的电解液中在0.15～0.55mol/L和1.0～5.5A的浓度、电流区域内进行微弧氧化.实验发现微弧只在一定的浓度-电流区域中发生,可用平面图直观表示;在不同的浓度-电流区域内,薄膜具有不同的形貌,据此将浓度-电流区域图进一步划...

| Abstract: | In this paper,the laws of technological parameters for tetragonal barium titanate films by micro-arc oxidation were studied.micro-arc oxidation was conducted by placing Ti plates into the electrolytes containing Ba2+ in the region of which concentrations were between 0.15 and 0.55mol/L and currents were between 1.0 and 5.5A.It turned out that micro-arc only occurred in some concentration-current region which can be directly indicated by plane graph,and morphologies were different in various concentration-cu... |
