ВЛИЯНИЕ ОЗОНА НА КОРРОЗИОННОЕ ПОВЕДЕНИЕ МЕТАЛЛОВ И СПЛАВОВ

Abstract

Research on the effect of ozone treatment on metal corrosion is presented in the article. The results of experiments on changes in the state of metals and steels when they are in aggressive environments in the presence of ozone are analyzed. In most cases, the ozone-air mixture has a negative effect on various metals and welded joints, increasing the rate of corrosion. Considering that recently the popularity of ozone technologies in all industries has been steadily growing, the massive use of ozone in agriculture is a matter of time. Therefore, there is a need to conduct research aimed at studying the corrosion resistance of various steels and alloys used in the agricultural sector. It has been analytically established that one of the most accessible alloying elements resistant to ozone treatment is chromium. However, its content in steel grades Steel 08kp, Steel 45, 45X, Steel 60S2, which are most widely used in agricultural engineering, ranges from 0.1 to 1.1%. This chromium content may be insufficient and therefore similar studies need to be carried out. It was established that the most common Steel 08kp showed sufficient resistance to aggressive environments in the presence of ozone as a result of the experiment, quite comparable with more expensive alloys. At the same time, the introduction of ozone into a solution of 70% acetic acid reduced the weight loss per unit area of steel grades Steel 08kp, Steel 45, 45X, Steel 60S2 by 2...7 times. This suggests that ozone blocks metal atoms and prevents exposure to aggressive environments.
