Abstract An initial study of the processing parameters affecting deposition quality of TI-6Al-4V was conducted using the LENS (TM) direct laser deposition system. The significant number of process variables presents a problem in determining relative effects. A few of the easily identifiable variables were isolated and the deposits were characterized qualitatively by comparison of layer adhesion, porosity, and dimensional accuracy. These characteristics were compared for each deposit while processing variables such as laser power, travel speed, and hatch spacing were varied. The results led to the development of a set of optimum processing conditions that produce a quality deposit. (Auth abstract) [References: 5]
