Brigita Abakevičienė: Surface Modification of Additively Manufactured Titanium and Ceramic Materials

Abstract

Additive manufacturing (AM) enables the production of complex titanium and ceramic components; however, the inherent surface roughness, porosity, and microstructural defects often limit their performance. Surface modification techniques play a crucial role in enhancing mechanical strength, wear resistance, corrosion behaviour, and biological response.

This seminar provides an overview of the physical and chemical characterization of titanium and ceramic materials fabricated using Direct Metal Laser Sintering (DMLS) and Lithography-Based Ceramic Manufacturing (LCM) technologies. Surface structural and physical properties were measured using various analytical techniques, including Industrial Computed Tomography (μCT), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Optical Profilometry (OP).
