Effect selective laser melting parameters Project Details
| Abstract |
Ti-6Al-4V alloy is widely used in medical and dental applications because of its excellent biomechanical compatibility. Selective Laser Melting (SLM) is a new technique for metal powder-bed additive manufacturing, and it provides more freedom in the design of material properties. Nonetheless, the way in which SLM process parameters, volumetric energy density (VED), and the resulting tribological properties of Ti-6Al-4V interact are not fully understood and has been the primary focus of prior studies. This research seeks to analyze VED and its direct relationship with the porosity, surface finish, density, and wear of Ti-6Al-4V. Samples from five different VED sets were examined. Results indicate that increased VED contributes to: greater material
densification, increased microhardness, and higher wear resistance. However, lower VED was associated with greater porosity and surface roughness. The friction coefficient of prepared samples ranged from 0.266 to 0.63. Wear tracks examined by Scanning Electron Microscopy (SEM) showed smoother surfaces from samples with optimized VED. These, along with acid-etched microstructures, demonstrated that precise control of VED in SLM is critical to achieving good tribological performance and service life cost reduction of Ti-6Al-4V components for the biomedical and industrial fields.
