CREATION OF A FUNCTIONALLY GRADIENT MATERIAL BY THE SELECTIVE LASER MELTING METHOD

  • Published:
Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

The paper presents the results of an experimental study of the microstructure and microhardness of a functionally gradient material fabricated from 316L stainless steel and tungsten carbide (WC) ceramic particles by the selective laser melting method. High-quality defect-free cermet coatings with different ceramic contents were obtained. Optical and scanning electron microscopy and energy dispersive analysis show that laser processing leads to dissolution of WC ceramic particles. The produced coating has a dendritic structure and contains iron- and chromium-based carbides. The coating microhardness is in the range HV0.3 = 280 – 430.
