Electrochemical Oxide Films Corrosion Properties Diagnosis System for the Thermal Power Equipment Heating Surfaces

Article Preview

Abstract:

This article describes the electrochemical diagnosys system of oxide films corrosion properties of the thermal power equipment heating surfaces. It was found that the formation of oxide films on carbon steel surface in boiling water includes active dissolution with subsequent thermal conversion of the dissolution products into iron oxide (II). Forming films properties such as porosity and roughness change in multi repeating way, which includes the alternation of loosening and consolidation processes.
