T/CSTM 00046.16-2018 Low alloy structural steel corrosion test - Part 16: Micro-area corrosion electrochemical test method guidelines
Basic Information
Scope
Main technical content: This section specifies the test principles, test equipment, test process, and test report for measuring and analyzing the electrochemical signals of localized areas at the micron or nanometer scale during the corrosion of low-alloy structural steel. This section is applicable to characterizing the sensitivity of the material surface current, local surface potential, local corrosion current, and local impedance before corrosion of low-alloy structural steel, as well as the initiation and development of localized corrosion and its mechanism; it is also applicable to quality control and process improvement during the manufacturing of low-alloy structural steel, and to the evaluation of the corrosion resistance of low-alloy structural steel components in service environments.
