The Kermetico ID gun is an effective instrument for spraying tungsten carbide and Hastelloy-type coatings.
The Kermetico HVAF AK-ID system is ideal for lining inside diameters of pipes, tubes, barrels, and cylinder bores which can be effectively rotated.
The gun provides uniform non-permeable wear and corrosion resistant cermet coatings with a spray rate of 5 kg / 11 lbs. per hour, achieving a tungsten carbide coating hardness of 950 HV300 in internal diameters less than 4” (100mm) and over 1,100 HV300 hardness in 4.0” (100 mm) and larger internal diameters. Internal bores down to just 80mm can be sprayed.
As seen in the representative micrographs below, the coatings are extremely dense, which allows us to recommend thinner coats than other coating processes require for wear and corrosion resistant applications.
Tungsten carbide (WC-10Co-4Cr) coatings sprayed with the AK-ID gun in 4.0” (a) and 4.5” (b) ID auger barrels
(a) 1,155 HV300, Porosity <0.1%; (b) 1,300 HV300, Porosity <0.1%
Kermetico also offer a Rotating Inside Diameter (ID) Gun for spraying Metals and Carbides into bores and internal diameters 100mm and larger.
Kermetico HVAF ID guns are advanced equipment for the thermal spray deposition of quality carbide and metallic alloy coatings to protect internal surfaces of industrial equipment from severe wear and corrosion.
As the Australian distributor for Kermetico HVAF/HVOF equipment, MSSA supply specialised equipment for the spraying of Internal Surfaces for Corrosion and Wear Resistance.
