“…The adhesion of the composite coatings to the underlying alloy was independent of the surface of the substrate preparation prior to coating deposition, and was the same for ground (with the use of 1200 grit sandpaper) and mechanically polished substrates. In previous work 55 on nano-hydroxyapatite/chitosan coatings electrophoretically deposited on the Ti-13Nb-13Zr alloy, it was found during TEM and XPS investigations that a thin oxide layer (thickness up to 10 nm) containing the same ratio of the concentrations of Ti, Nb and Zr was present on the coating/titanium alloy interface. We assume that the good adhesion of the composite Al 2 O 3 /PEEK coatings to the titanium alloy substrates in the present work is due to chemical bonds between the coating and the substrate covered by the oxide layer.…”

In this work, 45-120 μm thick, composite Al 2 O 3 /PEEK coatings were fabricated on the Ti-13Nb-13Zr alloy substrate using electrophoretic deposition. The anodic co-deposition of alumina and PEEK particles were investigated and discussed. The asdeposited coatings exhibited the uniform distribution of a nearly amorphous PEEK and crystalline alumina powders on the titanium alloy substrate. The morphology of PEEK in the coatings was changed by heating above the PEEK melting point from granular into dense coating matrix with semi-crystalline structure and spherulitic morphology. Scanning and transmission electron microscopy investigation of the coating microstructure revealed the presence of uniformly distributed Al 2 O 3 nanoparticles and their agglomerates within the PEEK matrix. Micro-scratch tests indicated that the coatings are characterized by excellent adhesion to the underlying substrate. The Al 2 O 3 /PEEK coatings significantly improved the wear resistance and reduced coefficient of friction of the Ti-13Nb-13Zr alloy during dry sliding, also in comparison with a polymer PEEK coated alloy. However, the wear resistance of the Al 2 O 3 /PEEK coated alloy during sliding in Ringer's solution was less than the PEEK coated alloy. The coatings increased the corrosion resistance of the alloy in Ringer's solution. The coatings were also found to be cytocompatible with Among biometallic materials, titanium alloys are increasingly used in medicine as implant material, due to their favorable mechanical properties, low elastic modulus, good electrochemical corrosion resistance and relatively good biocompatibility.1-4 Generally, β and near-β (including Ti-13Nb-13Zr) alloys have about 30% lower Young's modulus than that of two phase α+β alloys. 5 In the case of Ti-13Nb-13Zr alloy the elasticity modulus is reduced by Nb, 6 while Zr is neutral for both the α and β phase. The uses of all titanium alloys in applications exposed to abrasive wear in orthopedic surgery and traumatology, for example, in the head and acetabulum of hip endoprostheses, are limited. This is because of their relatively low hardness, low resistance to abrasive wear, high and unstable coefficient of friction (COF), severe adhesive wear and tendency to seize. 1,[7][8][9][10][11][12] Therefore, in order to improve the bio-tribological performance of titanium alloys, surface treatment is necessary.In recent years, polyetheretherketone (PEEK) coatings have often been applied as solid lubricant films in bio-tribosystems because of their notable wear resistance, corrosion resistance and self-lubricating capacity.13,14 PEEK, with a basic formula of (-C6H4-O-C6H4-O-C6H4-CO-)n, is a polyaromatic, semi-crystalline thermoplastic polymer exhibiting a superior combination of strength, stiffness, toughness and good biocompatibility. 15 Numerous studies have confirmed the successful clinical performance of PEEK for in vivo medical device applications, in orthopedic and spine implants. 13,[15][16][17][18] A number of studies [19][20][21] have also been conducted to d...

The corrosion behaviour of new generation titanium alloys (β-type with low modulus) for medical implant applications is of paramount importance due to their possible detrimental effects in the human body such as release of toxic metal ions and corrosion products. In spite of remarkable advances in improving the mechanical properties and reducing the elastic modulus, limited studies have been done on the electrochemical corrosion behaviour of various types of low modulus titanium alloys including the effect of different beta-stabilizer alloying elements. This development should aim for a good balance between mechanical properties, design features, metallurgical aspects and, importantly, corrosion resistance. In this article, we review several significant factors that can influence the corrosion resistance of new-generation titanium alloys such as fabrication process, body electrolyte properties, mechanical treatments, alloying composition, surface passive layer, and constituent phases. The essential factors and their critical features are discussed. The impact of various amounts of α and β phases in the microstructure, their interactions, and their dissolution rates on the surface passive layer and bulk corrosion behaviour are reviewed and discussed in detail. In addition, the importance of different corrosion types for various medical implant applications is addressed in order to specify the significance of every corrosion phenomenon in medical implants.

“…Among different Caps, HA [Ca 10 (PO 4 ) 6 (OH) 2 ] is widely used due to its osseous nature and suitability to strong bonding with host bone tissues . Different coating methods have been utilized such as plasma spraying, dip coating, hot isostatic pressing, ion beam‐assisted deposition, pulsed laser deposition, sol–gel technique and electrophoretic deposition (EPD) . Among of these methods, EPD has several benefits such as better control thickness and morphology of the coating, components with complex shapes are deposited uniform, higher deposition rate than other coating technics and cheap equipment required …”

In this research work, hydroxyapatite/alumina/YSZ bio nanocomposite coatings on titanium substrate were created by electrophoretic deposition (EPD) and reaction bonding process. By using the EPD process, uniform green form coatings containing HA, yttria-stabilized zirconia (YSZ), and aluminum particles were produced on titanium. After oxidation of aluminum at 660°C and sintering at 850°C, a dense and adherent HA/Al O /YSZ coating was produced. Scanning electron microscopy, X-ray diffractometric and mechanical tests were employed to investigate the morphologies, compositions, hardness, toughness and bonding strength of the coatings. The corrosion studies and cell culturing experiment were carried out and the results show that the HA/YSZ/Al O coatings are more bioactive and more resistance to corrosion than HA coatings. © 2018 Wiley Periodicals, Inc.
