Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Surface and Coatings Technology, In conclusion, a number of the surface modifications conducted have a beneficial affect on the wear resistance of Ti6Al4V. The process is also likely applicable to other metal/metal alloys such as CoCr, NiTi and stainless steels. Furthermore, the chemical-free nature and ambient temperature conditions concerned afford this process the potential to act as an attractive alternative to some of the more problematic high temperature approaches currently in use.

The cell culture of titanium alloy surface modifications by micro-powder blasting and co-blast techniques

“…The surface-modified Ti6Al4V substrate has a greater surface roughness than the non-surface-modified surface roughness. This results is very similar to reference [7]. Surface modification (micro-powder blasting) increases the surface roughness of Ti6Al4V substrate.…”

“…The results indicate that the surface roughness of Ti6Al4V increased with the increase of Al 2 O 3 particle size. The surface roughness of the Ti6Al4V substrate of SiC impact particles exceeded higher than the surface roughness of Al 2 O 3 impact particles of the same size This results is very similar to reference [7]. Surface modification (micro-powder blasting) increases the surface roughness of Ti6Al4V substrate.…”

“…G2 group compared with G1 group and G3 group, the new bone mass increased significantly after 4 weeks [6]. The wear and friction of a Ti6Al4V substrate that was combined with Al 2 O 3 and teflon, silicon carbide (SiC), or boron carbide (B4C) by blasting method was investigated [7]. The pretreatment of 9% Cr steel substrate surface by glass-bead blasting yielded an aluminised layer with a more uniform structure and less thickness variation than pretreatment by grinding [8].…”

Aluminum Templates of Different Sizes with Micro-, Nano- and Micro/Nano-Structures for Cell Culture

“…The antibacterial effectiveness of Ti substrate treated with pure HA particles or HA combined with zinc apatite (ZnA), silver apatite (AgA), or strontium apatite (SrA) particles were evaluated, and it was found that the substrate that was treated with HA and AgA performed best in this respect [5]. The wear and friction of a TiAl 6 V 4 substrate that was combined with Al 2 O 3 and teflon, silicon carbide (SiC), or boron carbide (B 4 C) by blasting method was investigated [6]. An MG63 cell culture was conducted on a Ti substrate after blasting with HA and sintered CaP particles.…”

Poly(NaSS) Functionalization Modulates the Conformation of Fibronectin and Collagen Type I To Enhance Osteoblastic Cell Attachment onto Ti6Al4V

“…Titanium (Ti) and its alloys are preferred in orthopedic applications when the implant material is in direct contact with bone. These materials possess excellent corrosion resistance, low toxicity, “acceptable” compatibility with the living tissue, and good mechanical properties, namely high tensile strength and durability, high ductility, and low density. ,, One drawback, however, is the possible aseptic loosening due to inadequate tissue response (i.e., fibrous tissue formation and/or infection) and integration of the implant . One of the approaches to address these problems is to chemically modify the surfaces of the implant, such as by grafting of bioactive polymers onto Ti substrates to create biomimetic surfaces.…”
