Abstract

This paper presents new results of studying the structure-phase compositions of Ni-based powder coating, deposited by Microplasma Spraying onto steel substrate by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X-ray diffraction (XRD). It is shown that we have managed to obtain the predicted specific structure with nanosized lamellas of intermetallic phases due to the appropriate proper selection of modes of additional microplasma processing. As a result, the microhardness of the coating has been increased by 1.25 times.
