An innovative fabrication of nano-HA coatings on Ti-CaP nanocomposite layer using a combination of friction stir processing and electrophoretic deposition

Fabrication and characterization of nano-HA-45S5 bioglass composite coatings on calcium-phosphate containing micro-arc oxidized CP-Ti substrates

“…Moreover, the bonding strength of HA-BG coatings are higher than that of HA coatings (~24 MPa); this value is higher than those reported for HA coated samples (7 to 11 MPa) [17,20,48].…”

“…On the other hand, the required time for formation of an apatite layer on HA-BG composites was obtained shorter than for HA, indicating higher bioactivity [7]. Among many methods have been applied to form bioactive films, such as plasma spray [8,9], sol-gel [10][11][12], biomimetic [13,14] and ion implantation [15,16], electrophoretic deposition (EPD) [17][18][19][20] is an effective technique for the fabrication of dense and uniform biomaterial coatings on a substrate even with complex geometries. Moreover, this technique has the advantages of high production rate and low investment cost [21].…”

Micro-scratch and corrosion behavior of functionally graded HA-TiO2 nanostructured composite coatings fabricated by electrophoretic deposition

“…As a result, the simultaneously enhanced biocompatibility and mechanical properties could be achieved by coating tough Ti-6Al-4V alloys with bioactive HA (Yang and Lui, 2008). Among different methods employed for the fabrication of HA-coated metallic implant, such as plasma spray (Laonapakul et al, 2012a;Laonapakul et al, 2012b;Rakngarm Nimkerdphol et al, 2014;Yugeswaran et al, 2012), sol-gel (Abdi Bastami et al, 2013;Tredwin et al, 2013), biomimetic (Liao et al, 2008) and micro-arc oxidation (Farnoush et al, 2015b), electrophoretic deposition (EPD) (Farnoush et al, 2012a, b;Farnoush et al, 2013b;Farnoush et al, 2013c;Farrokhi-Rad et al, 2014;Ozhukil Kollath et al, 2013) is an effective technique for the fabrication of dense and uniform HA layers on a substrate even with complex geometries. This technique has the advantages of high production rate and low investment cost (Corni et al, 2008;Ferrari and Moreno, 2010).…”

Defects Modification of TiB₂–TiC Composite Phase Coating Resistance Spot Welding Electrode via Friction Stir Processing

“…Bauri et al 4) employed FSP to improve in situ the microstructural and properties of an AlTiC composite using FSP technique. Famoush et al 5) fabricated nano-hydroxyapatite coatings on the Ti-CaP nanocomposite surface layer by FSP and electrophoretic deposition. Grewal et al 6) found that the friction stir processed (FSPed) hydroturbine steel (Fe13Cr4Ni, mass%) gave 2.6 times old improvement in micro-hardness and erosion rate as compared to unprocessed (unFSPed) steel samples.…”
