    This study explores the metal of a coating deposited by a high-chromium flux-cored wire alloyed with a BN-TiB2-ZrB2 complex. We investigated the changes in the durometric properties and fine structure of the coating after tempering and subsequent quenching. It is shown that the hardening of the metal of such a coating after quenching consists in the formation of a complex composite structure with an iron-chromium martensitic matrix, a large amount of eutectic and particles of hardening complexes, which leads to an increase in hardness and wear resistance. It has been established that phase transformations in the metal of such a coating are caused by the formation of an eutectic component based on chromium and iron borides, a framework structure and a large number of dispersed titanium nitride particles up to 2.5 μm in size.

    Modern society is developing in conditions of pressing social, economical and ecological problems. Since Russian big industrial business as part of society has an effect on its development, social responsiveness becomes increasingly important. Value of social responsiveness is in minimizing negative implications of company production operation, in solving climate, global and local development.
    Thanks to social responsiveness business becomes more well-established socioeconomically, gets an opportunity of increasing its intangible assets.
