Abstract

Hardfacing is of increasing importance in both reclamation and in strengthening of working surfaces. Determination of the serviceability of hard layers in various operating conditions requires a knowledge of their phase structure as well as the mode of overlays failure. Spectrochemical macroanalysis of hard layers showed desired composition of deposits and proved the correctness of the surfacing process. The hardness of layers reached 700 to 800HV. Martensitic-austenitic structure with numerous precipitates was observed. EPMA and EDAX analyses disclosed an equal distribution of alloying elements without signs of segregation. Identification of the second phase was carried out using X-ray and EB diffraction analyses. Carbides and borides of alloying elements have been observed using TEM. SEM analysis of fracture morphology of overlays provided some information about the correlation of microstructural and fractographic features of several overlays. The outcomes of the reported investigations allow conclusions to be drawn about conditions of applicability of hardfaced overlays.
