The basis of the system is the spraying of the metal or
metal alloy wire, which is directed to the flame formed by acetylene and oxygen
gas mixture, from a gun with the help of compressed air of molten or
semi-molten particles.
The most common coating materials are wire formed carbon steels,
alloy steels, stainless steels, aluminium, copper, bronze, cobalt, nickel,
molybdenum, tin, zinc, etc.
During coating, the temperature of the workpiece is kept
under control and distortions and dimensional deformation are not allowed.
Coating thickness over 5 mm can be obtained with this
system. High roughness coatings (ra: 20 µm) are the most obvious feature of the
system.
