In this study, the Laser Direct Metal Deposition technique was employed to deposit AISI 316 stainless steel powder on Ti6Al4V substrate. Microstructure characterization and composition distribution were studied by scanning electron and optical microscopy. The elements along the metal deposition were detected by the energy dispersive spectroscopy (EDS). X-ray diffraction (XRD) revealed a mixture of intermetallic compounds, which are responsible for the bond brittleness. The metal deposition had a complete wetting of the grain boundary matrix by the second phase.

Abstract

In this study, the Laser Direct Metal Deposition technique was employed to deposit AISI 316 stainless steel powder on Ti6Al4V substrate. Microstructure characterization and composition distribution were studied by scanning electron and optical microscopy. The elements along the metal deposition were detected by the energy dispersive spectroscopy (EDS). X-ray diffraction (XRD) revealed a mixture of intermetallic compounds, which are responsible for the bond brittleness. The metal deposition had a complete wetting of the grain boundary matrix by the second phase.
