摘要
采用极化曲线法和失重法研究了温度(250℃左右)和杂质氯酸钠对工业纯镍在沸腾氢氧化钠溶液中腐蚀行为的影响,结果表明:镍处于活性溶解状态,随着温度的提高,其腐蚀速度加快;氯酸钠作为阴极去极化剂可加速腐蚀。
The effects of temperature (about 250 ℃) and sodium chlorate impurity on the corrosion of industrial pure nickel in boiling sodium hydroxide solution were studied by polarization curve methode and method of weight loss.The results showed that nickel was in a dissolved condition and the rate of corrosion quickened with the increase of temperature,and that sodiun chlorate as depolarizer for cathode could accelerate the corrosion.
