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.
Problems of nondestructive carbon content in structural steels estimation are considered in this paper. These problems include complexity of carbon's distribution over the alloy's sample and significant variance of used electrochemical process inner parameters. Proposed solutions are adaptively adjustment of probe current pulses parameters and obtained data (chronopotentiograms) treatment algorithm based on decompositional modeling method. Experimental part contains application of both solutions to carbon content identifying. Efficiency of proposed adjustment of probe current pulses parameters is proved by comparing distinguishability of obtained this way chronopotentiograms to ones, obtained in uncorrected impulse mode.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
