Electricity is the backbone of our society. Everything that we run in our day-to-day lives requires electricity in some form or another. There are a lot of ways that electricity can be generated, and as we move to a net-zero society, more and more of these methods are sustainable. Electric cables and even the small wires in our electronics are usually made from copper as it is a good conductor and is not affected by oxidisation. When a metal is affected by exposure to oxygen or water, there is a need to use HVOF like that from www.poeton.co.uk/standard-treatments/plasma-coatings to protect the outer layer.
