THE INFLUENCE OF THE COATING ON HYDROGENATION, FRAGILITY DETERIORATION OF STEEL

The purpose of the work: the systematic study of the influence of the composition and structure of the different nature coating on its water permeability and the ability to protect steel from the hydrogenation, fragility and deterioration in the corrosion-active media, using the common methods. Established have been the parameters values of the water permeability of steel with the diffusion one-component and multicomponent coatings, allowing to prognose its efficiency as the protective means of steel against the hydrogenation, fragility and deterioration of steel. The values of parameters of the steel water-permeability with the diffusion one-component (Cu, Al, B) and multicomponent (B-Cr, B-Al, B-Cr-Al, B-Cr-Mo, B-Cr-Ni) have been established. All kinds of the diffusion coatings increase the steel resistance to the hydrogen-cracking coatings. The results of the work allow to perform the further work on creation of the new coatings. The results of the work have been introducedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
