摘要：
Potentiodynamic polarization measurement was used to investigate the effects of temperature,dissolved oxygen concentration and pH on the electrochemical behavior of X70 pipeline steel in simulated solution according to the orthogonal testing method.The results showed that temperature,dissolved oxygen concentration and pH had great influence on corrosion current density(icorr) of X70 steel.Corrosion current density of X70 steel was most influenced by dissolved oxygen concentration in simulated solution.The corrosion degree of X70 steel was the least under the environment of low temperature,deficient oxygen and weak acid.
