Plasma spray
Jun 01, 2018

BenefitsApplication & materialsProcess details

· Plasma spray is a thermal spray coating process used to produce a high quality coating by a combination of high temperature, high energy heat source, a relatively inert spraying medium, usually argon, and high particle velocities.

· Plasma is the term used to describe gas which has been raised to such a high temperature that it ionizes and becomes electrically conductive.

· The utilisation of plasma spray coating technology allows the spraying of almost any metallic or ceramic on to a large range of materials with exceptional bond strength, while minimising distortion of the substrate.

· As the technology specialists in plasma spray, Bodycote provides an array of thermal spray coating materials to suit your specific needs. Backed by a customer-driven service, our facilities process a wide variety of component sizes to exacting standards with reliable, repeatable results.


· The great advantage of the plasma spray coating technique is its ability to spray a wide range of materials, from metals to refractory ceramics, on both small and large components offering:

· corrosion protection

· wear resistance

· clearance control – abrasives and abradables

· heat and oxidation resistance

· temperature management

· electrical resistivity and conductivity

Application & materials

· Due to its versatility and excellent characteristics the plasma spray coating process is selected by many technologists as a process which offers the widest choice of coating materials.

· Fretting wear, spraying of tungsten carbide/cobalt seal ring grooves - gas turbines;

· High temperature protection, thermal barrier coatings -tbcs onto gas turbine combustion hardware;

· Wear resistance, spraying of chrome oxide ceramic onto printing rolls for laser engraving;

· Anti-galling, spraying of molybdenum alloys onto industrial diesel engine piston rings; and

· Erosion/abrasion resistance, corrosion protection – down hole tool - oil and gas product.

Carbides, metallics, ceramics, abradables.

Process details

· A plasma spray coating offers solutions to many different applications in low and high temperature environments.
