Formation features of microstructure, elemental and phase compositions of the C-Cr-Mn-V-Fe coatings under conditions of electron beam (EB) Surfacing in vacuum
The microstructure and interphase distribution of chemical elements in multilayer coatings made of white cast iron in Fe-Cr-V-C system additionally alloyed with manganese and obtained using electron-beam surfacing in vacuum have been investigated. It is shown that in deposited state the surface of Cr-V-Mn cast iron coating is represented by the composite structure of "austenitic manganese containing matrix - carbides V2C, Me7C3 of variable composition" with high abrasive wear resistance (Ki = 9.4) similar to chrome vanadium cast iron coatings with an austenitic-martensitic matrix, but with significantly better abrasive wear resistance compared to cast iron coatings with an austenitic matrix stabilized by nickel.
