用于电解器的表面改性的不锈钢阴极
Abstract:
工业上通过盐水的电解来生产氯酸钠，并且因此是一种能源密集型方法。一种用于这种以及其他工业方法的改进的阴极是一种低镍含量的不锈钢，该不锈钢的表面已被适当地改性。通过适当量的表面粗化，该阴极在仍然保持抗腐蚀性的同时，在电解过程中提供改进的过电压。
Abstract(English):

Sodium chlorate is produced industrially via electrolysis of brine and is thus an energy intensive process. An improved cathode for this and other industrial processes is a low nickel content stainless steel whose surface has been suitably modified. With an appropriate amount of surface roughening, the cathode provides for improved overvoltages during electrolysis while still maintaining corrosion resistance.
