Registration Date 22-01-2022 Organization Physico-Mechanical Institute named after GV Karpenko of the National Academy of Sciences of Ukraine popup.description2 The analysis of modern researches of tribocorrosion and methods of protection of materials against corrosion and mechanical wear is carried out. The basic approaches to definition of tribocorrosion mechanisms are resulted. The mechanisms of corrosion-mechanical wear and its patterns are difficult to interpret due to the synergism of the processes, because the friction changes the corrosion sensitivity of the material. The variety of operating conditions of friction units complicate the development of recommendations for improving the wear resistance of various parts for tribocorrosion, so each case requires careful study of the impact of working environment on the process and wear intensity of materials. The method of investigation of tribocorrosive properties of metals and alloys in a corrosive environment, containing hydrogen sulfide, was improved. The conditions of its concentration stability were provided.   Product Description popup.authors Ivashkiv Vasyl R. Vasuliv Khrystyna B. Vergun Igor A. Vynar Vasyl Andriyovich Dyachuk Alla I.
