| Popis: | Effects of plasma nitriding on oxidation behavior of 304 SS exposed in 290 °C high temperature and pressurized water have been investigated. The oxidation behavior of 304 SS with plasma nitriding was changed significantly after the exposure tests. Moreover, the nitriding time also had an obvious effect on the oxidation behavior. The difference in oxidation behavior was mainly due to the changes of pH value on the local area near the nitriding layer caused by the formation and hydrolysis of NH4+. The influencing mechanisms of the nitriding time on oxidation behavior in high temperature and pressurized water are also discussed. |
