Abstract

The Ni3Al intermetallics involve more attention because of inherent material properties especially interesting in high temperature application. In this study the Selective laser melting (SLM) and Direct laser metal deposition (DLMD) are used to manufacture the single-tracks and layers. For the comparison of the methods, the optical microscopy, SEM, XRD and EDX microelement analysis were involved. The materials show no significant differences but each SLM and DLMD have the target application.
