Abstract
The results of investigations of structure, hardness and wear resistance of iron-based alloys containing up to 4.5 % C and 15 % V are given. The dependence of structure and type of carbides on chemical composition of these alloys was studied. The analysis of effect of structure on wear resistance at abrasive wear of deposited metal, close by its composition to the investigated alloys, in initial state and after heat treatment was made. It was established that deposited metal of this type has a high wear resistance due to formation of martensite structure with small amount of residual austenite and with disperse, uniformly distributed carbides of vanadium and carbides of Me23C6 type. 6 Ref., 1 Table, 3 Figures.
