Enhancing tribological performance of Ti6Al4V with additively manufactured porous architecture: A scanning interval approach

This study explores the impact of additive manufactured porous architecture on the tribological performance of Ti6Al4V. Biomimetic porous architectures were manufactured on dense multi-layer using direct energy deposition with a dense layer followed by a porous layer. Varied scanning intervals during laser processing for the porous layer influenced the microstructure and, consequently, the hardness, the corrosion resistance and the tribological behavior of the dense layer. The results indicate a substantial improvement in tribocorrosion performance, particularly noteworthy in reducing corrosive wear rates, making porous architectures beneficial for both biomimetic structures and enhanced tribocorrosion resistance in body fluids.
