A short review of the recent electrolytic and electroless plating research trends for a variety of metal alloys deposited to improve corrosion resistance, wear characteristics and hardness, magnetic behaviour, catalytic properties and for other application areas, is presented. The review contains key references from the period 2008 to the present (mid 2011), although it is not exhaustive. One finding is that most of the studies highlighted appear to be focused on one or more application areas, rather than being mechanistic deposition process studies. In addition, applications other than corrosion and wear resistance seem to have inspired significantly more effort than hitherto.

Recent applications of SEM and AFM for assessing topography of metal and related coatings — a review

Recent literature describing the use of scanning electron microscopy (SEM) and atomic force microscopy (AFM) in the investigation of morphology and topography of metal surface coatings has been reviewed. SEM has been shown to give valuable data on many properties such as Þ lm uniformity, thickness and cracking, wear patterns and debris, and bond failures. In addition, much information is made possible on coating phase structure, grain size and boundaries, uniformity and heterogeneity, growth mechanisms and porosity. Combined with energy dispersive X-ray analysis and chemical mapping techniques, SEM can be especially powerful. The newer technique of AFM has some advantages over SEM; however, studies tend to focus on imaging nanostructures and quantitative determination of deposit surface roughness. Advances in the application of the technique are expected to further its use, for example, in the measurement of friction, adhesion and elasticity.

“…ZnMn alloys are difficult to plate in aqueous mediums due to the low reduction potential of manganese and to its reactivity [88]. These alloys, useful for corrosion protection, can be however obtained from choline chloride/urea mixtures [89] with good coating properties. On the contrary, Mo-based alloys are difficult to obtain in a wide composition range due to the inertness of molybdenum.…”

Deep eutectic solvents constitute a class of compounds sharing many similarities with properly named ionic liquids. The accepted deinition of ionic liquid is a luid liquid for T< °C) consisting of ions, while DES are eutectic mixtures of Lewis or "rønsted acids and bases. Their most atractive properties are the wide potential windows and the chemical properties largely diferent from aqueous solutions. In the last few decades, the possibility to electrodeposit decorative and functional coatings employing deep eutectic solvents as electrolytes has been widely investigated. " large number of the deposition procedures described in literature, however, cannot ind application in the industrial practice due to competition with existing processes, cost or diicult scalability. From one side, there is the real potential to replace existing plating protocols and to ind niche applications for high added-value productions to the other one, this paves the path towards the electrodeposition of metals and alloys thermodynamically impossible to be obtained via usual aqueous solution processes. The main aim of this chapter is therefore the critical discussion of the applicability of deep eutectic solvents to the electrodeposition of metals and alloys, with a particular atention to the industrial and applicative point of view.Keywords: electrodeposition, deep eutectic solvents, metals, alloys . IntroductionThe electrodeposition of metals for industrial surface inishing is nowadays a well-established industrial practice.

There are however some important limitations, as not all the metal/substrate combinations are possible in the current state of the art. This is connected to the nature of the electrolytes used for the vast majority of the plating processes, which are water based. Water is the most obvious choice to formulate a plating electrolyte, and in the majority of the cases, it is also the most convenient from the point of view of the results obtained. This solvent however presents some limitations: narrow potential window, reactivity towards speciic metals, high hydrogen evolution in speciic conditions, etc. If metal plating is limited to aqueous solutions, many possibilities are therefore precluded." possible way to extend the range of coating/substrate combinations is the use of non-aqueous solvents, characterized by ext...
