New Development of Arc Spraying Technology-Metal arc spraying

Metal spraying is the use of compressed gas to melt the molten metal into particles, spray deposited on the surface of the workpiece prepared in advance to form a complete metal coating. In general, there are three main uses of metal spraying:
(1) For anti-corrosion, high temperature oxidation or wear protective coating;
(2) It is used to repair the size of parts, such as the lack of geometric dimensions of the parts due to large-scale abrasion or local machining errors, which can be repaired by metal spraying;
(3) Metal-coated non-metallic materials are used instead of metal-made equipment or parts. Metal arc spraying is the use of AC or DC arc melting continuous feeding of metal spinneret, and then from the compressed air through the nozzle to atomize and spray the workpiece surface, the main device of the spraying process known as the metal arc spraying gun.
Russia's ВНИИТУВИД Institute has been engaged in metal arc spraying process and equipment for many years, at present it is in the summary, absorbing advanced experience at home and abroad based on the successful development of a high-performance type M-5 arc spray gun. Compared with similar devices, it has the following advantages: jet angle is reduced to 13 °, spray utilization increased by 25%, for φ2.4mm spinneret, spray coating process can reduce the weight loss of 30 to 40%; diameter of more than 100mm Cylindrical cylindrical parts, the inner surface of the spray depth of up to 400mm; The device uses a removable structure, and parts of the disassembly is relatively simple, so its maintenance is good; through the console for equipment operation is simple and convenient.
