Abstract
This paper describes LINDE’S Flame-Plating process and its supplement LINDE’S PLASMARC process. The Flame-Plating process utilizes the energy of oxy-acetylene detonations to obtain extremely high temperatures and propel particles of heated coating material onto the work piece at supersonic velocities. The coatings are widely used in applications where severe operating conditions are encountered, for instance: compressor blades, turbine blades, seals, hydraulic pumps and valve plates, bearings etc. The wide selection of materials that can be flame-plated makes the process especially attractive to the design engineer. The combination of light weight, low moment of inertia, and high wear resistance can be obtained by flame-plating aluminum, magnesium or titanium with tungsten carbide. LINDE’S PLASMARC process ensures that the flame coating maintains the metallurgical integrity of the coating material, thus not resulting in oxidation or carbonization. Although there is no direct measure of weight savings, LINDE’S processes increase operational life of coated parts, reduce material wear, and prevent the selection of heavier materials to overcome the industrial challenges.
