摘要：

Real time hot corrosion monitoring is still a challenging issue in coal-based power generation systems. It is not easy to achieve reliable and repeatable data such as quantitative relations between corrosion progress and data readings. This research work demonstrates an application of a new high temperature electrochemical sensor system with a reliable reference electrode to provide a clearer picture of the corrosion degradation. The hot corrosion behavior of a Ni-based superalloy was studied in the presence of a synthetic coal ash and a synthetic flue gas containing sulfur dioxide using our proposed high temperature electrochemical sensor.
