Wire flame sprayingprocess 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 ascopper, bronze,不锈钢, high carbon steel, molybdenum, and low melting point metals includingaluminum, zinc, and others.
TheFlame Spraying Processis basically the spraying ofmolten metalonto 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 thespraycontacts the prepared surface of substratematerial, 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.
- Thecoatingcontains 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.
