This paper describes the application of electroforming in the synthesis of nanocrystalline nickel by very high speed movement of the electrolyte; the principles and mechanisms of electroforming in the production of nanocrystalline structured metallic objects in combination with high speed movement of electrolyte are also described. Nanocrystalline nickel components were formed at a speed exceeding 600 μm per hour; the grain size of the electrodeposited nickel was considerably reduced by high speed movement of the plating solution. When requirements specify high-tolerances, complexity, lightweight and miniature geometry, electroforming is a serious contender and in certain cases may be the only economically viable manufacturing process. AFM characterisation showed that the crystalline/particle sizes of the electroformed objects were less than 30 nm. The nickel deposits were characterised further using SEM/EDAX. The focus of this study is primarily in the application of nanomaterials in industrial gas turbines.
Offshore wind installation vessel capacity to tighten after 2020
The existing fleet of turbine and foundation installation vessels is well suited to serve the European offshore wind market in the short and mid-term but it will not be sufficient to support installation demand after 2020, Michael Guldbrandtsen, senior consultant at MAKE Consulting, told Wind Energy Update. The next 2-3 years will continue to be dominated by orders for jack-up installation vessels, according to Guldbrandtsen. Purpose-built jack-up vessels are well suited for turbine and foundation installation...
Industrial Maintenance for Compressor Stations
Transporting natural gas via pipelines is very safe and cost-efficient. However, in order for the transportation process to work properly it is imperative that the natural gas be kept at the correct pressure. To accomplish this compressor stations are needed at regular intervals. Let’s take a look at some key components of compressor stations as well as industrial maintenance needs. The Components of Compressor Stations Compressor stations are outposts placed at various regular points along a natural gas...
Romax brings gearbox know-how to the aerospace industry - Case Study
A consortium of industry leaders, consisting of Romax Technology Ltd, ANSYS Inc, and the Gas Turbine and Transmissions Research Centre (G2TRC) at the University of Nottingham, has received Government funding for a research and development project that promises to play a pivotal role in maintaining the UK’s prominent technological and manufacturing position in aerospace. The funding is provided by the UK’s aerospace R&D programme, delivered in partnership between the Department for Business,...
Annual European Union greenhouse gas inventory 1990–2014 and inventory report 2016
ES.1 Background information on greenhouse gas inventories and climate change The European Union (EU), as a party to the United Nations Framework Convention on Climate Change (UNFCCC), reports annually on greenhouse gas (GHG) inventories for the years between 1990 and the current calendar year (t) minus two (t–2), for emissions and removals within the area covered by its Member States (i.e. emissions taking place within its territory).The present report is the official inventory submission of the European...
What’s the Future of R&D in the Wind Industry?
When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to the levels they were at leading into 2008. This will have an enormous and continuing impact on R&D. The year 2008 is...
