Plasma and Thermal Spray Coatings

Endless variety of performance characteristics

Plasma and thermal spray coatings can be sprayed on virtually any properly prepared surface and can use a wide selection of materials to impart an array of characteristics…ranging from electrostatic and electromagnetic shielding to electrical or thermal conductivity, from electrical insulation to thermal barriers and more.

PLASMA THERMAL APPLICATION OF POWDERED METALS AND CERAMICS

HOW IS IT APPLIED?

The plasma arc is hot ionized gas composed of nearly equal number of electrons and positive ions passing through an electrical arc. This plasma flame can reach temperatures upwards of 28,000 degrees Fahrenheit. Any powdered material that melts without decomposing, can be introduced into the plasma strewn at a precisely controlled amount. This molten material can be projected against the surface being sprayed at speeds in excess of mach two. The temperature of the base material is kept under 250 degrees Fahrenheit. This process can be performed on heat treated, and hardened parts without causing any distortion or changing of the parent material properties.

WHERE ARE SOME APPLICATIONS FOR SPRAY COATING?

SALVAGE: costly, as well as inexpensive parts can be saved by rebuilding a worn or mis-machined area back into dimension. Often this results in a part that will outwear the original by a factor of two to three times.

WEAR COATINGS: coating can be applied to resist abrasion, corrosion, erosion, fretting, friction, and galling. Parts can be manufactured for less money using a low cost base material, and applying a wear resistant coating in areas of need.

WHAT ARE SOME OF THE SPECIAL CHARACTERISTICS?

CHARACTERISTICS: Since plasma sprayed materials can be sprayed on virtually any properly, prepared surface, and using a wide selection of materials, the limitations are almost endless! Coatings can provide such characteristics as: electrostatic or electromagnetic shielding, electrical conductivity, electrical insulation, thermal conductivity, thermal barriers, and many others.

Magnesia alumina spinel coating

For parts requiring high thermal shock and gas erosion resistance, CCC-500 provides an excellent finish. It can coat alloys, ceramic, platinum, steel and spinel parts, and is widely used for surface molds, ladles, ladle plugs, ladle lids and other furnace parts. It provides gas erosion resistance and controlled permeability for oxygen sensors.

Wear Coating

For high structural integrity, and resistance to particle erosion, oxidation and temperatures up to 1,200 degrees F, CCC-210 is an ideal solution. It provides high bond strength, high tensile strength, high inter-particle cohesion and resists fretting, which is why it’s recommended for brake rotors, exhaust valve sets, wear rings, bearing seats, and more.

Wear-resistant super fine tungsten carbide coating

Applications requiring resistance to abrasion, erosion, sliding wear and fretting call for CCC-208. It provides a hard, dense coating with excellent bonding properties. It’s typically used for buff chucks, ultrasonic welding horns and wire drawing ring “pulleys”.

Wear-resistant super fine ceramic coating

For parts and components subject to wear by abrasive grains, hard surfaces, particle erosion and cavitation, CCC-212 provides a hard, dense, smooth coating with excellent abrasive wear properties. It’s an excellent choice for pump seals, plunges, buffing and polishing fixtures, exhaust fans, diesel engine cylinder liners, and other parts.

Thermal barrier coating system

To insulate and protect metal components from high temperature operating environments and thermal shock, CCC-400 (Link to PDF)is ideal. It reduces the component metal temperature, resulting in reduced creep stress, lower oxidation rates and greater component durability. It’s typically the choice for combustors, airfoils and augmenters in gas turbine engines and cylinder heads, piston crowns, and exhaust and intake valves in diesel and gas engines.

Plasma Coating Applications for Military & Aerospace

Aluminum polyester

For abradable surfaces of aerospace engine components, and particularly in the cooler compressor sections of the engine, an aluminum polyester coating provides the protection required.

Zirconium oxide

For the combustor and hot sections of engines, zirconium oxide delivers and excellent thermal barrier.
