Biofunctionalization of Ti6Al4V alloy with metallic agents like Ag or Cu is a promising approach to add antibacterial properties and thus reduce the risk implant failure. This research investigates in-situ alloying Ti6Al4V(ELI) 3 at.% powders using Laser Powder Bed Fusion (L-PBF). The morphology geometrical characteristics single tracks layers were studied. powers 170 W 340 W, scanning speeds ranging from 0.4 1.4 m/s 0.8–2.8 implemented. Single track results showed balling effect humping at...
The present article is intended to study the deposition mechanisms of bioactive hydroxyapatite ( HA ) particles by means Cold Gas Spraying CGS ). A comparison on two different substrates (Ti6Al4V and Al7075T6) particle sizes presented. Although this a more specific technique for ductile materials, it here shown that, in certain conditions, ceramic possible despite inherent low ductility. resulting internal structure features at particle–substrate interface are discussed view Transmission...
Abstract This article deals with the production of thick ceramic hydroxyapatite coatings obtained by Low Pressure Cold Gas Spray (LPCGS) system. Several factors such as powder microstructure, surface roughness and cold gas spray system are here discussed in build‐up process. The use nanocrystalline composed fine agglomerates needle‐like shape microstructure allows realignment compaction individual crystallites to form deposits. In addition, activation substrate results convenient for first...
Additive manufacturing is a good alternative to conventional methods for the production of near net shape geometries with high geometric complexity shorter lead times, being option dies die casting process. In this research, novel hot-work tool steel aluminum applications manufactured by laser powder bed fusion was investigated. As-built and stress-relieved (AS-B + SR) state established used as reference condition, subsequent post-treatments were added compared condition. Test parts...
In the present study, cellular lattice structures for implant applications are reported first-time incorporating copper directly by in-situ alloying in laser powder bed fusion process. The aim to incorporate 3 at.% Cu into Ti6Al4V(ELI) is selected improved antibacterial properties while maintaining appropriate mechanical properties. Previously, topologically optimized were successfully designed, manufactured and studied applications. development of a new alloy produced elemental mixture pure...
This article deals with the understanding of influence surface topography on fatigue behavior Ti6Al4V alloy specimens produced by laser powder bed fusion (LPBF). The same parameters and scan strategy were used for all specimens, giving a sample density higher than 99.5 %. Two different topographies obtained using top side surfaces specimens. morphology investigated optical profilometry focus variation microscopy. Four-point bending test was performed as highest stressed respectively....
Cold gas spray (CGS) titanium coatings have been produced to obtain porous and rough with enhanced mechanical performance. The from optimal spraying conditions reached tensile strength values up 40 MPa, shear 39 MPa a loss mass of 37 mg/100 cycles in abrasive testing, accordance the ASTM standards be applied for orthopaedic joint prostheses. An innovative hierarchical structure (micro-nano) consisted TiO2 nanotubes top layer obtained by anodisation onto CGS Ti coating. present paper focuses...
Cu addition to alloys for biomedical applications has been of great interest reduce bacterial growth. In situ-alloyed Ti6Al4V(ELI)-3at.%Cu was successfully manufactured by laser powder bed fusion (L-PBF). Even so, post-heat treatments are required avoid distortions and/or achieve required/desired mechanical and fatigue properties. The present study is focused on the investigation microstructural changes in L-PBF after stress relieving annealing treatments, as well their influence osteoblast...
Although a lot of in vitro and vivo assays have been performed during the last few decades years for hydroxyapatite bioactive coatings, there is lack exploitation real-time interaction measurements. In present work, interactions plasma sprayed coating were measured by Multi-Parametric Surface Plasmon Resonance (MP-SPR), results compared with standard traditional cell viability assays. MP-SPR proven to be suitable not only measurement molecule-molecule but also molecule-material measurements...
