Abstract
Background: The paper addresses the problem of improving the energy efficiency and durability of heat exchange equipment. Particular attention is paid to improving the characteristics of heat exchange surfaces of heat exchangers, which play an essential role in many industries. The range of issues of pollution and corrosion of heat exchange surfaces and the causes that led to them are discussed.
Objective: Analysis of the effect of ion implantation on the contamination and corrosion resistance of heat exchange surfaces of the heat exchange equipment.
Methods: Within the framework of this study, comparative analysis methods to record changes in the composition of the surface layer of the samples under study were used. Microhardness studies were carried out in the direction from the surface to the depth of the test sample using the Neophot-2 device on transverse metallographic sections, which were cut perpendicular to the implantation.
Results: During the study, the data on changes in microhardness of aluminum samples after nitrogen implantation were obtained, as well as the data on changes in the structural composition of surface layers and increased resistance to corrosion, contamination, and prolonged exposure to surfactants.
Conclusions: As a result of the study, it can be said that a decrease in energy efficiency due to contamination of heat exchange surfaces is more pronounced in heat exchangers in which a high value of the heat transfer coefficient was initially designed. Ion implantation not only increases the microhardness and wear resistance of materials, but also prevents the appearance of an oxide film, which in turn reduces the contamination of the heat exchange surface, and also makes the heat exchange surface less susceptible to prolonged exposure to surfactants.
