Investigation of the Efficiency of Fatty Acid Amides as Atmospheric Corrosion Inhibitors

Protection of agricultural machinery (AM) from corrosion at all stages of operation using anticorrosive agents is an important condition for increasing its service life, reliability and reducing costs for ensuring preservation. The unsatisfactory state of anticorrosive protection of AM is caused by a number of reasons. One of which is the lack of effective multifunctional corrosion inhibitors. The shortage of domestic inhibitors remains an important problem today. This is due, first of all, to the lack of a scientifically sound concept for their creation, as well as the lack of a raw material base. The cessation of production of such a product as synthetic fatty acids has led to a reduction in the market of a number of effective corrosion inhibitors. The authors have developed a technology for obtaining fatty acid amide (FAA) from triglycerides of plant, animal origin or fatcontaining waste. The aim of the research was to assess the effectiveness of fatty acid amide as an inhibitor of atmospheric corrosion. To ensure the reliability of the result, a comparative assessment of a number of currently used preservation materials was carried out using the methods specified in GOST 9.054-75.
