应用经典的失重法研究确定MHWRR屏冷系统缓蚀剂K_2CrO_4的使用浓度和屏冷系统首次使用时表面预处理工艺。用表面分析技术、电化学测试法研究K_2CrO_4的缓蚀机理。K_2CrO_4为阳极型缓蚀剂。在碳钢表面形成的Cr_2O_3,Fe_2O_3或其它Fe-O-Cr化合物增补和强化了碳钢表面的抗蚀性。
The application of classical weight loss method to determine the MHWRR screen cooling system corrosion inhibitor K_2CrO_4 concentration and screen cooling system first use surface pretreatment process. Study on Corrosion Inhibition Mechanism of K_2CrO_4 by Surface Analysis and Electrochemical Methods. K_2CrO_4 is anodic corrosion inhibitor. Cr_2O_3, Fe_2O_3 or other Fe-O-Cr compounds formed on the surface of carbon steel supplement and strengthen the corrosion resistance of the surface of carbon steel.
