吡唑的缓蚀作用及协同作用的研究

CORROSION INHIBITION AND SYNERGISTIC EFFECT OF PYRAZOLE WITH INHIBITORS OF BTA AND MBT FOR COPPER

利用循环伏安法和旋转圆盘电极研究了NaHCO3溶液中吡唑对紫铜的缓蚀作用,并对其与BTA,MBT之间的协同效应进行了初探.结果表明在0.05 mol/L NaHCO3溶液中吡唑在紫铜表面有着强烈的化学吸附作用,吡唑与BTA之间有着协同作用,而与MBT的协同作用不明显.

The corrosion inhibition of copper in 0.05mol/L NaHCO3 in the presence of pyrazole and the synergetie effect of pyrazole with BTA and MBT were studied using cyclic voltammetry techniques and rotating disc electrode. The results showed that the pyrazole was adsorbed on the copper surface and there was a synergetie effect between pyrazole and BTA, but it was not obviously between pyrazole and MIST.
