What Is Metal Spraying

The combustion wire thermal spray process is basically the spraying
Of molten metal onto a surface to provide a coating,
Material in wire form is melted in a flame (oxy-acetylene) and atomised using compressed air to form a fine spray,
When the spray contacts the prepared surface of a substrate material, the fine molten droplets rapidly solidify forming a coating.
When machined this coating is harder wearing than the original substrate.

Characteristics of wire flame spraying  Process Coating

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