Wire Flame Spray Gun

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 flame most common) 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.

Characteristics of wire flame spraying process coatings:
  • 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 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 high level of wearing resistance.

Common materials Sprayed:

  • Zinc and aluminium for anti-corrosion cathodic coatings on steel
  • Nickel/aluminium composite wire for bond coats and self-bonding coatings
  • Molybdenum for bond coats
  • Molybdenum for hard bearing applications, excellent resistance to adhesive wear, used on piston rings, syncromesh cones and journals.
  • High Chromium steel for many applications requiring hard and wear resistant coating
  • Bronzes, babbitt for bearing applications
  • Stainless steels, nickel and monel for anti-corrosion and wear
  • Aluminium, nickel/aluminium for heat and oxidation resistance
