Investigation of the steel surface by probe microscopy after exposure to a corrosive environment
The purpose was to identify the optimal conditions for the study of the surface of steel subjected to corrosion by probe microscopy. The choice of the probe microscopy method for the study of the steel surface is justified. The study of the steel surface by the comparative method of metallographic optical microscopy was carried out, optimal research conditions have been established. An aqueous solution of paper pulp in an acidic medium containing heavy metal ions was used as an aggressive corrosive medium, and 55X steel was used as a promising material. When performing the work, a problem was identified consisting in distortion and blurring of the images of the surface of the samples due to external influences and noise. According to the results of comparative experiments, structural changes on the surface of the sample were revealed, reasonable conclusions were made.
