TogglePlasma spray technology uses a state of matter known as plasma, which is a gas that is heated to such extreme temperatures that it becomes ionized and electrically conductive It becomes a high-energy state that is the right medium for applying protective coatings, as it has a combination of high temperature and controlled particle velocity. The process usually uses argon as the main spraying medium, as it has inert properties that make sure the coating has the right consistency.
Plasma spray coating is very versatile, so it is used in many different industries and can provide corrosion protection, wear resistance, and thermal management for products. In gas turbine manufacturing, it is used for applying thermal barrier coatings to combustion hardware and creating tungsten carbide/cobalt seal ring grooves. The printing industry uses chrome oxide ceramic coatings on rolls for laser engraving, and the oil and gas sector relies on plasma spray to protect tools against erosion and corrosion.
One of the strengths of thermal plasma spray is how it can work with a wide range of materials from metals to ceramics. The plasma spray can be applied to both small and large components while creating bond strength and minimal change to the substrate. It can be applied to carbides, metallics, ceramics, and abradable materials, with each having different industrial needs. Companies such as https://www.poeton.co.uk/surface-treatments/thermal-metal-sprays/plasma-coatings provide thermal plasma spray treatments.
Plasma spraying has many advantages that run beyond just protecting items. It can also be used with abrasives and abradables for heat and oxidation resistance and for the management of electrical properties. Plasma spray coatings are very important for products used in high-stress environments that need another layer of coating protection.
