Metal Spray

    Metal spray is another way Atlas Machine can serve you. For over 100 years Atlas Machine has built a reputation as a premiere provider of industrial machining services, equipment rebuilding, and component remanufacturing. Our expertise in industrial coatings has given us the ability to provide protection from corrosion and wear to parts and components through our metal spray processes. Each of the processes we utilize has specific advantages. Our engineers and skilled craftsman will help you select which process and which of the wide variety of materials fit your specific needs.
High Velocity Oxygen Fuel (HVOF)The HVOF is fueled by propylene and oxygen with compressed air softening the particles that are carried by nitrogen onto the surface being sprayed. The gun features a combustion chamber that actually expands the products going through a small orifice in the gun at high velocities producing "shock diamonds" exiting the nozzle. Gas velocities have been reported exceeding Mach 1 using this process. HVOF coating are very dense and produce an extremely high tensile bond strength. Atlas Machine uses this process on steel mill roll bodies, piston rods, internal pump surfaces, and as a replacement to chrome plating

Powder Flame Spray

Powder flame spray is the simplest of all the spray processes. Powdered metal is melted in a flame and is sprayed to the ground surface of the required part. The main advantage of this process is the wide variety of materials that are available. Atlas Machine uses this process on sealed areas of shafts and crankshafts, engine block decks, main bores and caps.

Plasma Arc Spray

Plasma arc spray is spraying molten material onto a surface to provide a coating. A powdered material is injected into a very high temperature plasma flame where it is melted and accelerated to a high velocity. The hot material impacts the part surface and cools forming the coating. The advantage of plasma arc spray is it can spray very high melting point materials including ceramics. Atlas Machine uses this process for grinder spindles, piston rods, and seal areas on shafts.

Electric Arc Spray

For electric arc spray, two electrically charged wires come together and are melted at the arc point. The molten material is forced by compressed air and propelled towards the component. A wide variety of wires are available and most of the chemistries requested can be matched. Atlas Machine uses this process on trunnions, pistons, and rolls that require a lot of build up or rough coat finishes for traction.

Finishing

Coatings can be finish-ground and polished to your specifications, including super-finishing, using our state-of-the-art equipment. Craftsmen who work in Atlas grind shop have decades of experience and are utilized exclusively for this critical area of our business.
