Additive Manufacturing of Multi Layered Bioactive Materials with Improved Mechanical Properties: Modelling Aspects

Multilayered laminate structures obtained by coating of ultrafine-grained metallic materials with bioactive and multifunctional composite coatings are considered for biomedical applications. Laser-assisted densification multiple using laser cladding selective melting is an alternative route to reduce the risk early implant failure allowing faster cheaper fabrication. To understand cooperative relationships between different factors that cam influence manufacture such laminates reflecting in their bioactivity mechanical properties, multi scale numerical modelling applied. This work presents resent advances on development integrated models including generation, solidification powder bed, considering surface flow, wettability, tension other physical phenomena, specific thermo-mechanical aspects microstructure evolution.
