What is Wire Flame Spraying Process?

Wire flame spraying process uses metals and alloys in wire form as its spraying materials, and combustion flame or electric arc as its heat source. The molten materials are sprayed onto the surface of the subject to form the coating. All metals and alloys in wire form are available for the material, such as copper slag, bronze, stainless steel, high carbon steel, molybdenum, and low melting point metals including aluminum, zinc, and others.

The Flame Spraying Process is basically the spraying of molten metal onto a surface to provide a coating. The material in wire form is melted in a flame(oxy-acetylene flame most common) and atomized using compressed air to form a fine spray. When the spray contacts the prepared surface of substrate material, the fine molten droplets rapidly solidify forming a coating.

• The subjects to be sprayed are not affected by high temperature, which keeps the dimensional stability and morphological stability, causes no cracks, no strength reduction.
• The coating with a broad range of its thickness is available.
• The coating contains harder particles than those of original materials and hard ingredients including metal oxide, nitride, carbide and etc., which provide a high level of wearing resistance.
