Abstract
Results of experimental studies of the effect of different powdered boron-containing materials (amorphous boron, boron nitride, boron trioxide, boron carbide and iron-chromium-boron master alloy) contained in self-shielded flux-cored wire on structure, hardness and crack resistance of high-carbon deposited metal are given. It is shown that deposited metal alloyed with boron, using the iron-chromium-boron master alloy, has the most favourable physical-mechanical properties.
Keywords: arc surfacing, flux-cored wire, deposited metal, microstructure, microalloying with boron, hardness of deposited metal
