Some materials, such as ceramics, require a tremendous amount of energy to soften and transform into the desired coating. Materials like this are heated in the plasma stream at temperatures around 16,500° C and subsequently sprayed at Mach 2 speeds onto the surface to be coated.
The inherent versatility and control of the process permits the deposition of a wide variety of spray materials including metals, alloys, ceramics (oxides, carbides), and cermets. Such coatings offer excellent properties for abrasion, high temperatures, corrosion, electrical conductivity, EMI shielding, release properties, and repair of worn parts.
Nearly any material may be plasma sprayed, and since the substrate temperature can be properly controlled to stay below 250°F, there’s no fear of overheating that causes warping or deformation to the part being coated.
