What is Electric Arc Spray Gun?
In an electric arc spray gun, the attached material is dissolved while getting into the electric arc spray Gun as two wires. The compressed air flow stimulates the melted substance and sprays it on the prepared surface of the machine part. Added material like metalizing wires can be both from the same substance or another composition. Using nitrogen can decrease the oxidation of such surfaces.
Electric Arc Spray Coating Process
Electric Arc spray coatings are produced by a thermal spray coating method in which electricity melts two charged feedstock wires. An air or gas jet evaporates the melted metal into droplets that are moved onto a substrate surface to create a protecting coating/equipments. Electric arc spray coating is a flexible method that is quickly adapted to the requirements of various purposes. It is easy and inexpensive to perform on-site.
An air stream through the end of the metalizinggunatomizes and propels the heated particles towards a processed surface. With flexible parameters including voltage and amperage, arc temperatures can reach 5000° C, hot sufficient to melt any substance, at the very time the part surface remains cool. The arc spray coating method is estimated energy efficient because all of the input voltage is used to melt the spray substances.
