DEVELOPMENT OF METHODS OF STUDY OF CORROSION-MECHANICAL FRACTURE OF REINFORCING STEELS IN HYDROGEN-CONTAINING ENVIRONMENTS
The article is devoted to the development of a comprehensive methodology for the study of corrosion-mechanical destruction of reinforcing steels during their tests for longterm strength in hydrogen-containing media. It is shown that depending on the conditions of hydrogenation (temperature and chemical composition of the corrosive medium, type of polarization), the mechanical properties of the reinforcement change dramatically in the initial period of the experiment. With a further increase in the holding time in a corrosive environment without polarization, there is no significant change in mechanical properties. The most stringent experimental conditions (characterized by a minimum time to failure and a sharp drop in mechanical properties) are realized under conditions of simultaneous cathodic hydrogenation and application of tensile stresses to the sample.
