... temperature and high pressure corrosion environments were stimulated, and the effects of temperature on corrosion and the characteristic of corrosion product film of API 5CT P110 steel were discussed by using SEM, XRD and weight loss methods. The result shows that the corrosion rate of API 5CT P110 steel...

.... The noise resistance shows a decrease in corrosion rate during the first hour and keeps relatively constant in the rest of the time. During the first hour when inhibitor and corrosion product films are established, localized corrosion is observed 3 times and lasts about 80s each time. This may be due...
