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. © 2011 Institute of Metal Finishing.

A review of the current research and potential applications for pulsed current electrodeposition is presented. The influence of modulated current on copper plating from acid sulphate solutions is described by Leisner et al. The characteristics of pulse electrodeposited PbS thin films for narrow energy gap semiconductors is investigated by Thirumoorthy and Murali. Photosensitive SnS thin films 350 nm thick have been achieved by pulse electrodeposition with pulse on/off durations of 10 s. Nickchi et al. have fabricated low friction bronze-graphite nanocomposite coatings containing 30 nm sized graphite particles by pulsed current electrodeposition. The feasibility of growing nanostructured films composed of cobalt and yttrium hydroxide/oxide phases by electrodeposition from particle free aqueous solutions containing YCl 3 and CoCl 2 salts and glycine is also demonstrated.

The literature on pulsed current deposition over the past 3 years has been examined. The research effort extends over a wide range of metal and alloy systems, with the greater number of publications refl ecting existing and developing importance industrially, e.g., nickel and its alloys, copper for printed circuit boards, composite plating and nanomaterials. However, other applications are approaching industrial production, and there is a clear need for modelling, simulation and statistical experimental design to be introduced to aid the transfer of research results to industrial adoption. © 2010 Institute of Metal Finishing.

Levels of export activity, R and D commitment, and the different process mixes comprising different sectors, this last at both the level of main technology process groupings described in manufacturing classification SIC 2561, and when breaking down aqueous surface finishing into some of its major subprocesses, have been compared for different national subcontractor surface finishing sectors. Where possible, changes over the decade to 2010 have been identified. © 2012 Institute of Metal Finishing.
