| Abstract Scope |
Hybrid manufacturing, combining additive and subtractive manufacturing, allows for the complexities of additive manufacturing with the finish and accuracies of subtractive manufacturing. Hot wire-laser direct energy deposition uses a metal wire, made of the same alloy or a different alloy as the base metal, to build desired shapes, or repair damaged tools. Optimizing the printing process, including direction of the wire in each layer, and examining the corrosion behavior is necessary, especially to repair chemically affected tools. The research presented here will compare H13 steel specimens printed bi-directionally, with the wire moving back-and-forth along one axis, using a Mazak VC500A/5X AM hot wire deposition system. The H13 samples were printed in the XY and Z directions, along the 0, 45, and 90 axes, producing different defects and affecting corrosion behavior. The steel samples were exposed to a corrosive environment, then examined for changes in weight, thickness, appearance, and tensile strength. |
