Surface contamination and corrosion are the most serious problems for developers and enterprises operating industrial equipment, in particular heat exchangers. This paper studies the effect of surface properties (roughness and free energy) on the formation of crystalline, biological and paraffin deposits, as well as on the corrosion process. Designed for heat engineers involved in solving theoretical and applied problems of heat and mass transfer. The publication can be useful for students studying in the direction of "Heat Engineering and Heat Engineering," "Nuclear Energy and Technology," "Physics."
