Over the last few years, plasma spraying has skyrocketed in popularity across the globe to become the preferred thermal process in a variety of industries. This method utilises a highly energetic plasma jet to melt and accelerate material particles to form a protective coating for components. The process begins by injecting feedstock material (usually in powder form) into very hot plasma (formed by the generation of a high-density arc current in the space between cathode and anode filled with molecular or mono-atomic gases) where it is rapidly heated and accelerated to a very high velocity. Once ejected onto the substrate surface, the molten material cools rapidly to form a high-quality coating.

Engineered Performance Coatings (EPC) is a leading specialist in developing and applying thermal spray coatings. They have used plasma arc spraying, HVOF and other thermal processes to apply coatings to components in a variety of industries. Here, they explore the benefits of using the plasma spray process.

A highly flexible process

Plasma spraying is a thermal spray process that can easily be adapted to give you the results needed for every job and component. For example, when you decide to use the plasma spray coating process, you have the freedom to choose from a wide range of quality coatings that suit your unique needs and budget. The vast majority of these materials come in powder form and include pure metals, alloys, abradables and ceramics.

If you need more evidence of plasma spraying’s flexibility, just consider the fact that the process can be applied using a wide variety of powder particle sizes (unlike many other processes of thermal spraying coating) to cover a huge range of substrate surface materials (e.g., metals, plastics, ceramics, glass, etc.)

Looking after your components

The main aim in applying a plasma coating to a substrate surface is to provide a high-quality protective barrier to the substrate, which in turn increases the lifespan of the component. Plasma spraying is a very effective way of making sure that the surface of the substrate material is insulated, controlled, and has a high resistance to corrosion, oxidation and everyday damage.

It’s easy to see why plasma spraying is enjoying rising popularity; this innovative technology is effective, versatile and economical, making it an excellent choice for most industries and applications.
