Features
The compact Kermetico HVAF AK5 system is used to deposit tungsten and chromium carbides, stainless steels, Hastelloy, Inconel and Ni-based coatings onto complex surfaces of various parts and structures. It is a heavy-duty coating system, made to sustain harsh environments and to work long hours with high spray rates. The AK5 spare parts consumption is ten times less than HVOF (both volume- and cost-wise). This is because the temperature of air-fuel combustion is 1,000 °C (1,830°F) lower than oxy-fuel. The parts of the gun are not heat-stressed. Furthermore, the powder is fed axially and does not touch the nozzle walls during spraying thanks to our well-calculated gun geometry.
- Spray rate – 15 kg/hour (33 lbs./hour).
- Spray powders: cermet compositions 1-15 to 5-30 microns; metals and alloys 10-30 to 10-45 microns.
- Axial powder injection.
- With 80 kW power, we have designed it for spraying thin walls, internal surfaces, and parts having low heat dissipation.
- Fuel gas options: propane, propylene, natural gas, propane-butane, MAPP.
- Air cooling (no need for a water chiller) makes the system mobile.
- Sprays inside diameter 255 mm (10”) and larger.
- ID rotating version for inside diameters is available.
- Blast & spray operation saves 99% of blast media, 30-50% setup and preparation time.
- High coating quality: high density, low level of oxidation, impermeable to gas and liquids.
