“…From Section 5 it could be realized that the list of potential materials is currently somehow limited because of mechanical and biocompatibility requirements. Therefore, much attention has been paid to surface modification approaches [6,8,33,37,39,354,355,356,357,358]. Yet, coatings are of limited use because many of them may be subjected to wear in vivo.…”

“…Figure 1 illustrates some applications of metallic biomaterials. One example is the vascular stents made of stainless steel or shape memory alloy (SMA), sometimes coated with a polymer for drug eluting [6]. The global coronary stents market size was estimated at USD 9.3 billion (milliard) in 2016 and is expected to reach USD 15.2 billion by 2024.…”

Corrosion of Metallic Biomaterials: A Review

Metallic biomaterials are used in medical devices in humans more than any other family of materials. The corrosion resistance of an implant material affects its functionality and durability and is a prime factor governing biocompatibility. The fundamental paradigm of metallic biomaterials, except biodegradable metals, has been “the more corrosion resistant, the more biocompatible.” The body environment is harsh and raises several challenges with respect to corrosion control. In this invited review paper, the body environment is analysed in detail and the possible effects of the corrosion of different biomaterials on biocompatibility are discussed. Then, the kinetics of corrosion, passivity, its breakdown and regeneration in vivo are conferred. Next, the mostly used metallic biomaterials and their corrosion performance are reviewed. These biomaterials include stainless steels, cobalt-chromium alloys, titanium and its alloys, Nitinol shape memory alloy, dental amalgams, gold, metallic glasses and biodegradable metals. Then, the principles of implant failure, retrieval and failure analysis are highlighted, followed by description of the most common corrosion processes in vivo. Finally, approaches to control the corrosion of metallic biomaterials are highlighted.

“…In recent decades, significant efforts have been made to prepare thin films of non-conductive and non-electroactive materials by indirect electrochemically induced deposition. This method is based on the electrochemical generation of species that are likely to react with precursors in solution in the vicinity of the electrode, leading to the deposition or growth of solid phases onto the electrode surface mainly driven by local pH changes [51,86,89,121,[128][129][130][131][132][133][134][135][136][137]. This is conceptually distinct from electrophoretic deposition, i.e., a technique involving the application of an electric field to a solution containing suspended matter, leading to the deposition of charged particles onto a conductive substrate [138], which was mainly applied to the formation of metal oxide and ceramic coatings [139][140][141][142] or the deposition of other advanced (bio)materials [143][144][145].…”

“…In the present case, a reagent is generated via an electron transfer reaction at the electrode surface and sogenerated species are involved in subsequent reactions inducing the transformation of solution-phase precursors (via precipitation or polycondensation) into a desired material coating the electrode support. Examples are available for metal oxides [129,130], polymers [131,132], sol-gel derived materials [133,134], layered double hydroxides [89,135], ordered mesoporous thin films [51,86,128,136,137]. They can be formed according to different driving forces.…”

Electrodeposition is a long-lasting and efficient process to generate thin or thick films on conductive supports. It is mainly based on electrochemically induced redox reactions involving electroactive precursors, which are intended to form solid deposits onto the electrode surface. More recently, a rather counterintuitive approach has emerged by exploiting electrochemistry to generate non-electroactive and non-conductive thin films (e.g., sol-gel derived materials), based on the electrogeneration of a catalyst that is likely to induce indirectly the formation of a thin film (i.e., without direct electron transfer with the precursors). This account summarizes the major advances made by our group in this field, focusing primarily on electro-induced sol-gel bioencapsulation and electroassisted self-assembly of oriented and functionalized mesoporous silica films.

“…Some time ago [13], typical coating methodologies were the ion beam assisted deposition, plasma spray deposition, pulsed laser physical vapor deposition, magnetron sputtering, sol-gel derived coatings, electrodeposition, micro-arc oxidation, and laser deposition. In [14], described methods such as electrodeposition, electrografting, micro-arc deposition, electropolymerization, and electrophoretic deposition of polymers, metals, metal oxides, and ceramics on surfaces of titanium, stainless steels, magnesium alloys, and cobalt alloys were described In another paper [15], the review on surface treatment of titanium alloys focused on anodization mentioning the plasma electrochemical oxidation (PEO) method. In [16], the sol-gel and electrochemical deposition methods were described for many covered metals.…”

Coatings deposited under an electric field are applied for the surface modification of biomaterials. This review is aimed to characterize the state-of-art in this area with an emphasis on the advantages and disadvantages of used methods, process determinants, and properties of coatings. Over 170 articles, published mainly during the last ten years, were chosen, and reviewed as the most representative. The most recent developments of metallic, ceramic, polymer, and composite electrodeposited coatings are described focusing on their microstructure and properties. The direct cathodic electrodeposition, pulse cathodic deposition, electrophoretic deposition, plasma electrochemical oxidation in electrolytes rich in phosphates and calcium ions, electro-spark, and electro-discharge methods are characterized. The effects of electrolyte composition, potential and current, pH, and temperature are discussed. The review demonstrates that the most popular are direct and pulse cathodic electrodeposition and electrophoretic deposition. The research is mainly aimed to introduce new coatings rather than to investigate the effects of process parameters on the properties of deposits. So far tests aim to enhance bioactivity, mechanical strength and adhesion, antibacterial efficiency, and to a lesser extent the corrosion resistance.
