摘　　要：利用静态高温高压釜及电化学腐蚀试验装置 ,通过失重法及极化曲线研究了裸样J5 5油管钢及其镍磷镀防腐层的抗CO2 腐蚀性能。结果表明 ,镍磷镀层的抗CO2 腐蚀性能好于裸样 ,其自腐蚀电位较之裸样有明显正移 ,其腐蚀速率约为裸样的 1/ 10。Using an apparatus for the static high temperature and high pressure corrosion test and electrochemical measurement technique, CO_2 corrosion behavior of J55 steel and its Ni-P coating are investigated by weight-loss method and electrochemical polarization technique.The results shows that the resistance to corrosion of Nickeling and Phosphoring steel is better than that of the bare sample-J55 steel obviously,its corrosion velocity is almost one percent of the bare sample.
