Abstract—The possibilities of confocal laser scanning microscopy (CLSM) methods for estimating the parameters of crevice and pitting corrosion of austenitic chromium–nickel AISI 316L steel after corrosion tests in aqueous media with various chlorine ion contents are estimated. Saturated and diluted artificial seawater with various chlorine ion contents in the range from ~100 to ~29 000 ppm is used as a corrosive medium, and the corrosion test time ranges from ~1000 to ~4200 h at temperatures of 25 and 70°C. Corrosion tests and CLSM studies have found that the foci of crevice corrosion form at a chlorine ion content of more than 7300 ppm in water at both test temperatures and all exposure times, and the formation of corrosion sites with metastable pittings is only detected after the maximum test time at 70°C and the maximum Cl– content of ~29 000 ppm.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
