“…We have previously demonstrated fiber laser surface modification of CP-Ti and Ti6Al4V using a continuous wave (CW) 200W fiber laser system at 1064nm, reducing the initial bacterial adhesion of S. aureus and also exerting a bactericidal effect ( Chan et al., 2017 ). Other studies have shown laser-texturing of Ti6Al4V using a Nd:YVO 4 laser with a wavelength of 532nm to improve bone implant contact to a similar level as hydroxyapatite-coated and grit-blasted implants in ovine models ( Coathup et al., 2017 ), and laser engineering as a technique used to affix biocompatible compounds such as hydroxyapatite to the surface of the orthopedic implant as a means of improving osseointegration ( Chien et al., 2014 ; Mukherjee et al., 2017 ).…”

Summary Titanium and its alloys have emerged as excellent candidates for use as orthopedic biomaterials. Nevertheless, there are often complications arising after implantation of orthopedic devices, most notably prosthetic joint infection and aseptic loosening. To ensure that implanted devices remain functional in situ , innovation in surface modification has attracted much attention in the effort to develop orthopedic materials with optimal characteristics at the biomaterial-tissue interface. This review will draw together metallurgy, surface engineering, biofilm microbiology, and biomaterial science. It will serve to appreciate why titanium and its alloys are frequently used orthopedic biomaterials and address some of the challenges facing these biomaterials currently, including the significant problem of device-associated infection. Finally, the authors shall consolidate and evaluate surface modification techniques employed to overcome some of these issues by offering a unique perspective as to the direction in which research is headed from a broad, interdisciplinary point of view.

“…Mukherjee and co-authors discuss the lase surface remelting process and explores the effects of different process parameters on microstructural, topographical, tribological and bio-interfacial aspects of biocompatibility of Ti alloys. The limitations associated with laser surface remelting processes were also identified [5]. Magnesium (Mg) and its alloys have been gaining a lot of attention for its potential application as biodegradable metals.…”

“…In addition to laser cladding ceramic coatings, laser remelting has been investigated to improve the biocompatibility of Titanium and its alloys. The results proved positive, showing that the biocompatibility of the material can be improved by remelting the substrate to control the topography, microstructure, and surface oxide composition of the material [12,13]. It is unknown if this will also be in effect when a ceramic coating is added to the melt.…”

In this study, the laser cladding process was utilised to deposit a thick ceramic layer of TiO2 onto a Ti6Al4V metal alloy substrate to improve the wear properties at the surface. A custom made powder was compared to a commercially available powder and testing was completed at high scan speeds with increasing laser powers. The results showed that Marangoni convection occurs in the clad melt which will affect the properties of the surface treatment. The custom powder was found to have a less consistent track formation than the commercially available powder, but its track dimensions were much more suitable for producing a full surface layer. The custom powder was found to have less defects such as cracking, porosity and delamination compared to the commercially available powder. Increasing the laser scan speed increased the height and width of the clad track, while lowering the contact angle. However this did slightly increase the number of defects within the clad layer.
