Benefits of technology

The present patent is about a thermal spray coil that can be used with a wire arc thermal spray machine. The coil is made of a specific material called FeAlSi, which has a certain amount of aluminum, silicon, and iron. The technical effect of this invention is that it allows for the creation of a reliable and compatible coil for thermal spraying, which can help improve the efficiency and accuracy of the process.

Problems solved by technology

Such materials of the thermal spray wire may fail to oxidation when applied to the metallic component with 800 degree Celsius operational temperatures.

Embodiment Construction

[0009]Referring to FIGS. 1 and 2, there is shown an exemplary turbocharger 10 that may be required to operate at a temperature of about 800 degree Celsius. The turbocharger 10 includes a flange portion 12 that connects the turbocharger 10 to an exhaust manifold (not shown) of an engine (not shown). The flange portion 12 includes an external surface 14, and is made up of a metallic material. The metallic material may be, but is not limited to, aluminum, steel, iron casting, and / or the like. With continuous and prolonged operation, the external surface 14 of the flange portion 12 may wear out and the thickness of the flange portion 12 may decrease. In order to correct the thickness of the flange portion 12, and reuse the turbocharger 10, the flange portion 12 of the turbocharger 10 may require to be remanufactured. Although reference to the turbocharger 10 are made, concepts of the present disclosure should not be limited to the turbocharger 10 and may extend to any metallic component...

Abstract

A thermal spray coil, shaped and sized to be compatible with a wire arc thermal spray machine, is disclosed. The thermal spray coil includes a wire of FeAlSi material. The wire includes 0.5 to 6 percent aluminum, 4 to 7 percent silicon, and a remaining balance of iron.

Description

TECHNICAL FIELD[0001]The present disclosure relates generally to a thermal spray coil employed in a wire arc thermal spray machine. More specifically, the present disclosure relates to a specific composition of a wire of the thermal spray coil employed in the wire arc thermal spray machine.BACKGROUND[0002]Various remanufacturing processes, such as a wire arc thermal spray process, are commonly known to refurbish and / or remanufacture used metallic components. In the wire arc thermal spray process, a wire of coating material is generally melted and applied on a metallic component to build up a surface that no longer satisfies the dimensional specifications of the metallic component. For instance, in case of a turbocharger, the thickness of a flange portion of the turbocharger may decrease with prolonged usage. Therefore, in order to remanufacture the turbocharger by the wire arc thermal spray process, the wire of coating material may be melted and applied on an external surface of the...
