| 摘 要： | 利用电化学电位噪声方法检测了不同腐蚀状态304与316两种不镑钢管焊缝区试样在室温碱液中的腐蚀行为,并采用电化学噪声时域谱、频域谱进行了分析,结果表明:不同腐蚀状态焊缝试样的腐蚀电位及噪声时城谱特征不同,可利用电位噪声频城谱的高频斜率K值定性判定是否发生局部腐蚀,同时可根据频城谱中发生事件特殊频率fn区分材料的腐蚀状态...

| Abstract: | The electrochemical potential noise(EPN) was used to check the weld zone of 304 and 316 stainless steel specimens in different states at room temperature in the 50% NaOH solution in order to deal with their different corrosion behaviors.The different-state specimens were made in the boiling 50% NaOH solution.Several EPN parameters were obtained from time domain and frequency domain analysis.The results show EPN of different corrosion states of weld specimens can be applied to ju-dging whether local corrosio... |
