为了提高涂层钛阳极(DSA)的导电性能,改善电化学催化性能,使其外层仍保持Ti的耐腐蚀性和电化学性能,从基体材料的组成结构入手,提出了以铝为内心,外层由钛包覆的层状复合电极材料。并根据材料复合技术理论,采用真空上引吸铸工艺,成功制得了理想的DSA层状复合材料。在铝液温度为780℃,模具温度为250℃时,界面结合良好。所制得的Ti/Al复合材料可以很好的改善电极的导电性能、催化性能,同时保持原有的耐腐蚀特性。
In order to improve the conductivity of the coated titanium anode (DSA), improve the electrochemical catalytic performance, and maintain the corrosion resistance and electrochemical performance of the outer layer of Ti, starting with the composition of the matrix material, The outer layer is covered by titanium layered composite electrode material. And according to the theory of composite material technology, the vacuum induction casting process was used to successfully obtain the ideal DSA layered composite material. In the molten aluminum temperature is 780 ℃, the mold temperature is 250 ℃, the interface is well bonded. The prepared Ti / Al composite material can well improve the conductivity and catalytic performance of the electrode, while maintaining the original corrosion resistance.
