铁的析氢腐蚀实验探究

Experiment Inquiry on Hydrogen Evolution Corrosion of Iron

针对析氢腐蚀实验中出现的异常现象,依据金属电化学腐蚀原理,通过实验探究确定影响析氢腐蚀实验的主要因素——氧气。在此基础之上,设计出演示吸氧腐蚀、析氢腐蚀的套管实验以及析氢腐蚀的微型化实验方案。

Aiming at the abnormal phenomena in the experiment of hydrogen evolution corrosion in the textbook of Jiangsu Education Press,oxygen was found to be the main factor that affected the hydrogen evolution corrosion experiment through experimental inquiry,based on the principle of electrochemical corrosion of metals.And then this paper designed schemes of casing tube experiments for hydrogen evolution corrosion and oxygen absorption corrosion,and microscale experiment of hydrogen evolution corrosion.
