Abstract

Whenever metals and metal-based materials interact with their environment (chemically, biochemically, or electrochemically), surface loss occurs, a process termed as corrosion. Corrosion is one of the important challenges which leads to the reduction of product life. In recent years, due to the growing interest of the world in protecting the environment and the harmful effects of using chemicals on ecological balance, the traditional approach with respect to corrosion inhibitors has gradually changed. Azole compounds have received a lot of attention in the oil, gas, and petrochemical industries since their structures prevent corrosion in acidic and alkaline environments. Also, due to having elements such as nitrogen and sulfur in their structure, they have been used widely as anti-fungal and anti-bacterial materials in the pharmaceutical industry as well. In this study, azole organic compounds, the encapsulation methods, and the mechanism of action of these compounds on the corrosion behavior of metallic surfaces have been investigated.
