“…Particles of similar size were also reported in tribological studies of TiN and CrN coatings. 7,17 Although massive exposure of substrate alloy suggests subsequent release of Co and Cr ions, we were unable to confirm this since serum samples were not obtained at the time of revision procedure.…”

Massive failure of TiNbN coating in surface engineered metal‐on‐metal hip arthroplasty: Retrieval analysis

et al. 2015

This article presents examination of a failed total hip replacement with surface engineered metal-on-metal (MoM) articulation. The implant was coated with a thin TiNbN film (Physical Vapor Deposition), and at retrieval 53 months after implantation the coating was abraded on weight-bearing part of the head and acetabular component. Scanning electron microscopy of bearing surfaces demonstrated multifocal crack formation, delamination of small film fragments, and formation of aggregates containing nanometer sized wear debris. We also observed coating damage in third body mechanism. Complex failure mechanism of TiNbN coating demonstrated in this study suggests insufficient bonding strength between the coating and substrate alloy and raise concerns regarding the use of such coatings in total hip arthroplasty with MoM bearing. © 2015 Wiley Periodicals, Inc.

“…In biomedicine as well as in other applications, the surface microstructure modification and/or coating have been assessed as strategies to improve the surface properties of Ti alloys. Physical and chemical vapor deposition (PVD and CVD) have been explored as coating processes to produce ultra-hard films on Ti alloys [4][5][6], but also recently other processes as DC reactive magnetron sputtering [7,8], electrodeposition [9], nitriding [10], laser surface treatment [11], solid state diffusion [12] and ion implanting [13], have been also proposed. Most of those techniques are limited by requirements of "atmosphere" or "pre-placement", complexity or high cost, making these processes difficult to implement in practice.…”

A B S T R A C TThe hardness and corrosion resistance of TiN coatings, processed by Electrophoretic Deposition (EPD) to cover polished and unpolished Ti substrates, have been evaluated. A deposition time of 5 min has been enough to obtain a cohesive layer of 7-8 μm in thickness. The coatings were thermally treated in vacuum atmosphere at 1200°C for 1 h with heating and cooling rates of 5°C min The nanohardness values of the polished samples have been increased from 2.8-4.8 GPa up to 6.5-8.5 GPa. Besides, the corrosion current density has been reduced more than one order of magnitude obtaining a protective efficiency of 82%. These values have been compared with other works in literature where authors used complex and costly processing techniques, demonstrating the strong impact of the colloidal processing over the specific properties of the material.

“…A good example is performed on orthopedic materials used to produce hip, knee or dental prostheses [1][2][3]. For such application, the coatings are required to be not only chemically stable, in order to produce biocompatible materials, but must also possess good mechanical, tribological and antibacterial properties to prevent implant failure [4].…”

Structural and electrochemical characterization of Zr–C–N–Ag coatings deposited by DC dual magnetron sputtering

et al. 2014

ZrCN coatings with incorporated silver were deposited on 316L stainless steel by dual reactive magnetron sputtering to evaluate the silver influence on the structural properties and corrosion resistance of the films. Samples composition was assessed by electron probe microanalysis.Glow discharge optical emission spectroscopy was used to determine the distribution of silver in the films. Structural characterization was performed by X-ray diffraction and Raman spectroscopy. Corrosion resistance was evaluated by potentiodynamic test and electrochemical impedance spectroscopy. Results revealed enhanced corrosion resistance properties of the coated steel and higher coatings reactivity when incorporated with silver, showing a plausible silver release increment.
