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

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).…”

Stacked Bioglass/TiO2 nanocoatings on titanium substrate for enhanced osseointegration and its electrochemical corrosion studies

“…The HCA phase that forms on bioactive implants have equivalent chemical and structural nature similar to the mineral phase in bone [11]. In the present study Bioglass 45S5 system is chosen to improve the osseointegration of the implant material, as this material possesses both osteoconductivity and osteoinductivity properties [12][13][14]. Even though Bioglass 45S5 has superior biocompatible properties it has poor mechanical properties and hence it could not be used for high stress applications like hip and knee joint prostheses.…”

Electroless Ni–B Coating of Pure Titanium Surface for Enhanced Tribocorrosion Performance in Artificial Saliva and Antibacterial Activity

“…Thus, numerous strategies focusing on the surface modification of Ti alloys have been employed to render them protection from both wear, corrosion and even tribocorrosion [3][4][5]. The strategies include physical vapour deposition [6], thermal spray [6,7], ion or laser nitriding [8][9][10], thermal oxidation [11,12], micro-arc oxidation [13][14][15], diffusion [16] and anodic oxidation treatments [17]. On the other hand, the antibacterial properties are also necessary for Ti implant RESEARCH when exposed to the living tissue [18].…”
