Laser powder bed fusion of Ti6Al4V-xCu: Process parameters

The original intent of coating biomedical and surgical devices surface with antibacterial agents is to prevent infections. However, the difference in material properties between materials causes spall from devices. To address situation, current research focused on investigating possibility using laser powder bed fusion process a subset additive manufacturing technology situ alloy 1 at% Cu Ti6Al4V. In alloying Ti6Al4V would lead production medical inbuilt property. determine optimum parameters that could be used manufacture Ti6Al4V- alloy, single tracks were produced over wide range powers scanning speeds analyzed. Process 170 W, 1.0 ms-1 hatch distance 80 µm identified as possible for alloy. Rescanning was good strategy improve roughness, homogeneity concentration matrix.
