STUDY OF MECHANISM OF ELECTROCHEMICAL REACTION FOR TITANIUM ALLOY TC4 IN 3%NaCl SOLUTION AND ETHANOL BY POLARIZATION CURVE
混合缓蚀剂对铜合金腐蚀性能的研究

The cathode and anode Tafel slopes of titanium alloy TC4 in 3%NaCl solution and ethanol were much greater than 0 118 V.It was difficult to explain the phenome na by traditional electrochemical mechanisms.We thought that the cathode process was controlled by the process H~++1/2 e = 1/2H~+ 2 was the very point to exp lain the cathode Tafel slope was about 0 23 V.And in anode process the nonstoic hiomet ric oxide TiO 1+X (0 5
