If you are looking to protect specialised equipment or popular household items, a plasma coating is an excellent choice. With myriad applications for this type of coating, it is a highly versatile and practical choice thanks to its ability to be micrometres or millimetres in thickness.
About this type of coating
One of five different types of thermal spray coatings, the efficacy of plasma spray coating is highly impressive. To create a spray coating of plasma, the method involves putting a working gas mixture through an electrical arc. The process discharge from this electrical arc is created in the minute gap between a cathode and an anode, which produces a fast energy release that turns the gas mixture into the plasma. This is released at a temperature of 14,000K and the process is similar to the technique known as flame spray coating.
The substance – often a powder, but other materials such as ceramics may also be used – impacts with the substrate surface to be covered. Once cooled, this delivers an incredibly hard, strong and durable layer of protection.
Due to the nature of the materials and the extreme temperatures involved, the process is extremely complex and can potentially be hazardous; therefore, it must be carried out in a specialised environment. The best way to obtain such a coating for your parts or equipment is to collaborate with an expert in such procedures, such as Poeton, that has many years of experience in coating a wide range of items.
How can this coating be used?
There is almost no end to the ways in which a plasma coating can be used. One incarnation of this type of spray coating, Teflon, is a household name that is praised for its protective and non-stick properties on items such as frying pans. Other domestic items that feature plasma coatings include common beauty appliances, such as hair straighteners, and even pet toys that require extra robustness for rough play.
Away from the home, the coating process is used in the aerospace and automotive industries, for medical and dental implants, and for coating the turbine combustion chambers of solar panels in the energy sector; in fact, it is hard to find a sector within the engineering or petrochemical industries in which plasma coating is not used.
