FORMING MECHANISM, STRUCTURE AND PROPERTIES OF BORIDE LAYERS ON STEEL

The purpose is the development of formulations and temperature conditions for obtaining boride layers capable of withstanding high contact loads. The optimum formulations of boride mixtures have been developed to permit enhancing the wear resistance of heavy-loaded friction assemblies. The effect of the components of the borating medium, i.e. a modifying mixture, graphite and iron powders in various weight proportions on the structure and properties of the boride layers has been analysed for the first time. The results of the investigations have been introduced as the process of hardening drill bit journals at the KYIBYSHEVBURMASH Joint-Stock Company; the scientific data have been applied at fulfilling the SIBYR (Siberia) practical scientific program, as well as the Program aimed at realizing the scientific investigations in the national economy. The field of application is the parts of the tooling, drill pipe strings, stamping tools, etc.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
