Powder Flame Spray Gun
This process is based on a similar operating principle as the wire flame spray process, with the difference that the coating substance is a spray powder. Thus, a bigger selection of spray materials is available, as not all spray elements can be manufactured in wire form.
Powder Flame Spray Gun
In powder flame spraying, the spray material in powder form is melted or fused in an oxy-acetylene flame and propelled onto the prepared workpiece surface with the help of expanding combustion gases. If necessary, an additional gas (e.g. nitrogen) are often used to accelerate the powder particles. The range of spray powders available is enormous, comprising well over 350 different kinds. Powders are classified as self-fluxing and self-adhering. Self-fluxing powders normally require additional thermal post-treatment. In most cases, this “fusing” step is applied using oxy-acetylene torches, which are extremely well-suited to the present task. The adhesion of the spray coating to the bottom material is greatly enhanced by the heat treatment, rendering it impervious to gases and liquids. This substance does not come into direct contact with the oxy-acetylene flame. A powder-feed sand blasting nozzle is located within the center of the flame spray gun. This is surrounded by two ring-shaped nozzle outlets, the inner ring being for air or inert gas, and the outer ring for the thermal energy source, i.e. the oxy-acetylene flame. The element is therefore not melted directly by the flame, but by the heated air and radiation heat. The mobility of flame spraying with powder, e.g. its use on-site, makes it frequently accomplished in its application.
Properties of Coating Powders
When a substance is a flame-sprayed, new and complex material is produced. This is the reason that the quality of the thermal spray gun coating depends upon the quality of the powder. A small variation in the powder can greatly affect the property of the last layer. The particle size distribution in a powder can change the density plus porosity of the coating. Then, Powder meets the best examples of chemical composition, particle shape & size, flow rate & purity.
