A flame spray gun consists of anozzle in which a combination of oxygen and fuel like acetylene, propane, orhydrogen is injected. The gas mixture is combusted in the front of the nozzle to make a flame external to the nozzle. Counting on the ratio of oxygen to fuel, the temperature of the flame ranges between 3000 and 3300°C. The selection of the nozzle design depends on the coating material, which may be in the form of either powder or wire. Powder FlameSpray Gun
A cold air cover is used tocollimate the flame to regulate the spray pattern. In the powder feed system,the coating material is gravity fed to the gun from a sand blasting hopper. The powder particles melt during the transition through the flame and deposit on the substrate.
Within the wire feed system, thewire tip is continually fed into the flame by a roller drive mechanism. Themolten material at the tip of the wire is fragmented and propelled to the substrate by compressed gas injection. The wire diameter and feed rate, air and gas flow rates, flame temperature, and pressure determine the coating properties.
Types of Flame Spray Gun
· Wire Flame Spray Gun
· Powder Flame Spray Gun
Wire Flame Spray Gun
In a Wire Flame Spray Gun, the oxy-fuel flame is used to melt the wires. To generate aspray of a stream that applies to coat on the surface to spray on an entity. ASpray gun is for spray both ferrous & nonferrous material. Important applications are restoring worn-out components, conductivity, and anti-corrosion coating.
Powder Flame Spray Gun
The main benefit of this methodis that a much wider variety of materials (such as nickel or cobalt-based selfFixing composites or ceramic substances) can be easily treated into powder form providing a greater choice of coatings. Many compounds are difficult or cannot be presented in a wire form and for this purpose, it was produced.
