FUSED METALS INC.
PLASMA SPRAY
A wide variety of metals, carbides, and ceramics can be deposited by the plasma process. Metals can provide corrosion protection, part restoration and mismachining correction. Ceramic coatings provide wear resistance, electrical insulation and thermal barriers. Carbides provide wear and abrasion protection. Coupled with our vacuum furnaces, fused carbide coatings provide a formidable protective shield.
PROCESSING
Thermal spraying generally consists of feeding a material into a heat source, melting it, and accelerating it towards a target. In plasma spraying, the feedstock is a fine powder and the plasma flame is both the heat source and accelerating medium. The plasma flame is created by passing an electric arc through an inert gas in a gun shaped apparatus. The plasma, as it is known, is created when the inert gas atoms are stripped of their electrons by the arc. When the plasma exits the gun, the electrons recombine with the gas atoms and a tremendous amount of energy is released. This energy results in a plasma flame burning at temperatures of up to 13000 C , with spray velocities approaching Mach 2.
With these conditions the plasma spray process is capable of depositing the widest rang of materials. Bond strength and coating integrity are maximized, while porosity and oxide inclusions are minimized.
As a quality driven supplier, Fused Metals Inc. is able to handle single pieces or large quantities with either manual or robotic coating capabilities.
