Extreme Coatings
Extreme Coatings™
The Concept
Surface Engineering’s Extreme Coatings™ process utilizes emerging Thermal Spray technologies to apply extremely wear resistant coatings to virtually any substrate. Our process produces crack free coatings in thickness of 0.001"-0.060" with hardness values ranging from Rockwell 55-75 on the "C" scale. We incorporate proprietary compositions of Carbides, Ceramics, and Alloys to achieve thermal, abrasive, and corrosive resistant characteristics unmatched by any of the conventional hardfacing alloys popular today! The process provides for smooth coatings that are uniform in thickness, and in the most cases, can be used in the "as applied" state. During the process, target components rarely exceed temperatures of 350°F permitting a broad spectrum of applications.

The Process
Extreme Coatings™ expands on the natural tendency for a molten particle of material to bond mechanically to another material upon impact and rapid solidification. A comparison may be to that of a weld splatter droplet adhering to its base metal. Our process harnesses the extremely high temperatures and forces of gas combustion to transform ultra-fine particles, typically less than 0.003" in diameter, into molten droplets traveling at speeds in excess of 2400 feet per second. Upon impingement, the particles flatten, solidify, and form an inter-locking bond within themselves and the pre-treated substrate. Deposit densities exceed 90% , and in some cases approach the 100 percentile. Virtually any material available in powder from can be applied via the Extreme Coatings™ process.

Applications Include:
Injection/Extrusion Screws & Barrels
Turbine Components
Bushings
Shafting
Mixer Blades & Paddles
Chutes
Fan Blades
Conveyers
Slurry Pumps
And many others...
Extreme Coatings™ applications may be limited however, to moderate impact conditions as coating bond strengths maximize at 12,000 PSI.
