In order to improve the performance of metal deposited with PP-Np-50Kh2MNSGF flux-cored wire, boron-containing FKhB-1 binder was added to the wire charge in such a way as to obtain boron content on the level of 0.01 % in the deposited metal. The effect of adding FKhB-1 binder to the flux-cored wire charge on its welding-technological properties was studied experimentally. It was found that application of boron-containing binder in the flux-cored wire charge does not impair its welding-technological properties, boron microalloying leading to refinement of the deposited metal structure and increases its hardness from HRC 53…57 to HRC 60…62 at the same content of other alloying elements. Developed PP-Np-50Kh2MNSGF flux-cored wire is proposed for deposition of wear-resistant layers for protection of parts of special machines and mechanisms in mining, metallurgical and other industries, operating under the difficult conditions of abrasive wear in combination with intense shock loads. 11 Ref., 2 Tabl., 4 Fig.
