Evaluation of Biological Properties of Electron Beam Melted Ti6Al4V Implant with Biomimetic Coating In Vitro and In Vivo
BACKGROUND High strength porous titanium implants are widely used for the reconstruction of craniofacial defects because of their similar mechanical properties to those of bone. The recent introduction of electron beam melting (EBM) technique allows a direct digitally enabled fabrication of patient specific porous titanium implants, whereas both their in vitro and in vivo biological performance...
متن کاملStructural Integrity of an Electron Beam Melted Titanium Alloy
Advanced manufacturing encompasses the wide range of processes that consist of "3D printing" of metallic materials. One such method is Electron Beam Melting (EBM), a modern build technology that offers significant potential for lean manufacture and a capability to produce fully dense near-net shaped components. However, the manufacture of intricate geometries will result in variable thermal cyc...
متن کاملPrevention of Hydrogen Embrittlement in Steels
The essential facts about the nature of the hydrogen embrittlement of steels have now been known for 140 years. It is diffusible hydrogen that is harmful to the toughness of iron. It follows, therefore, that the harmful influence of diffusible hydrogen can be mitigated by preventing its entry into steel or by rendering it immobile once it penetrates the material. This review deals with the meth...
متن کاملOnline Monitoring of Electron Beam Welding of TI6AL4V Alloy Through Acoustic Emission
Acoustic Emission (AE) Technique is the only Non Destructive Testing (NDT) method that can be thought of to be used as an online monitoring tool for detection, location and characterization of various kinds of active defects during any process. An effective approach of quality control is defect detection during welding process itself rather than by NDT of component after welding. Weld defects g...
متن کاملElectron Beam Melted (EBM) Co-Cr-Mo Alloy for Orthopaedic Implant Applications
The Electron Beam Melting (EBM) manufacturing process is emerging as an additional method for producing orthopaedic devices in several materials, including Co-Cr-Mo Alloy. This work presents the chemical, microstructural and mechanical properties of several test specimens produced by the EBM process before and after a post‐EBM Heat treatment. Comparisons are made to the properties of Co-Cr-Mo m...
