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.

HERE 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.
