Directed Energy Deposition of stainless steel wire with laser beam: evaluation of geometry and affection depth
Fabrizia Caiazzo, Vittorio Alfieri
Abstract
This paper is aimed at investigating the process of Directed Energy Deposition of steel wire to the purpose of maintenance and repair: this technology is receiving increasing interest in the frame of Additive Manufacturing and has been investigated for different metals and different substrates. An experimental plan has been designed here to investigate the dependence of the geometry on the governing factors in single-track deposition and quantify the depth of the affection in the substrate in terms of geometrical dilution and variation of the micro-hardness.
