摘要
将含有ＴｉＢ２、碳纤维和热固性粘结剂的涂料，涂敷到铝电解槽的阴极基体上，制备出可润湿的阴极表面。经固化和碳化后，涂层和碳质基体材料的粘结力强，热膨胀匹配性好。每台硼化钛涂层阴极试验槽能节省ＮａＦ２５０～３００ｋｇ，试验槽的电流效率高出对比槽１．４４％。
Cathode coating TiB 2, carbon fibre and thermosetting binder were coated on the matrix of the cathode in aluminium reduction cell to prepare aluminium wettable cathode surface. By cure and carbonization, this coating was characterized by strong bonding to cathode matrix and good thermal expansion match. NaF could be saved by 250～300 kg when TiB 2 coating was applied in a cell; current efficiency of the test group was 89.54%, which was 1.44% higher than that of compared group, and energy saving was 175～211 kW·h/t Al.
