Thermal spraying by oxygen, acetylene and hydrogen combustion. This technology is mainly aimed at the AEROSPACE industry.
The coatings are made of powder or wire.
TYpEs OF COATING
- Abradable coatings and metal alloy coatings for the aerospace industry
In this method, a controlled DC electrical current arc is used to melt two consumable electrodes (wires) which constantly approach so that the arc remains continuous. The melted particles are atomised, accelerated and driven towards the surface of the part by a pressurized gas, which can be either compressed air or inert gas.
ApPlicaTIONS AND COATINGS:
- Dimensional recovery
- Resistance to abrasion and seize-up (molybdenum)
- Chemical corrosion resistance (Al, Zn, NiCrMo)
