Wire flame spraying

Wire flame spraying is a thermal coating process that is used to apply protective coatings to various surfaces. In this process, a wire of the coating material is fed through a special spray gun, where it is melted in a burner flame. The molten material is then propelled onto the workpiece as fine particles using compressed air or another gas, where it is deposited and forms a coating.

Wire flame spraying is often used to protect components from corrosion, wear or high temperatures. The protective layers usually consist of metals, alloys or composite materials such as zinc, aluminum or their mixtures. It is particularly suitable for large-area coatings or repairs to damaged surfaces.

One advantage of wire flame spraying is the versatility of the process: different materials can be processed and even irregular geometries can be coated. In addition, the coating is applied without significant thermal stress on the substrate, which prevents deformation or material changes. Applications include the automotive industry, mechanical engineering, power generation and shipbuilding, where durable and resistant coatings are required.
