无参比恒槽压法导电涂层阴极保护技术的研究

无参比恒槽压法导电涂层阴极保护技术，甩掉了恒电位法使用的石墨参比电极，克服了用石墨参比电极电位不稳定时对阴极保护电位的影响，当涂层各部位干湿状态不均匀时，能自动调节各部位（干湿态）所需的极化电流密度ｉ阴（表现），使Ｅ槽压和Ｑ阴保护电位恒定不变，电位分布均匀，保护效果提高。此外，无参比恒槽压导电涂层阴极保护技术与恒电位法相比，还具有安装维护方便，运行可靠等优点，能广泛地适用于工业大气、海洋大气（潮差

Study of Cathodic Protection of Conductive Coating of Constraint Cell Voltage ( without reference electrodes)

The cathodic protecion of conductive coating of constraint cell voltage without reference electrodes has got rid of the grephytic referencial electrodes used in constant potential method. Thus overcoming the affects on cathodic protection potentials caused by unstable potentials of grephytic electrodes. If applied, when there is uneven state between wetness and driness , this technique can self-regulate thepolarization current density--i, required by each area (wet or dry) thus enabling the protection potentials of E Constraint Cell Voltage and q, remain unchanged with the potentials distributing evenly and high protection efficiency is thus maintained. Compared with constant potential method, this technique has such advantages as being convenient in maintenance, reliable in operation. It can be widely used in the environments with technical atmosphere and marine atomosphere (wet and spleshing), therefore convenient to spread.
