IMPROVEMENT OF THE PHYSICOMECHANICAL PROPERTIES OF GASTHERMAL COATINGS OF AN Fe-Cr-B-Si SYSTEM BY LASER DOPINGO. V. D'yachenko UDC 621.891:621.793 The influence of the regimes of laser treatment of gasthermal coatings of iron-based powders after fusion with modifying dopes on their microhardness and microstructure has been investigated. The conditions of production of coatings with the most uniform distribution of dopants have been revealed.
