Electric Arc Spraying
An electric arc burns between two metallic wires, which produces molten particles of material. These particles are propelled by compressed air towards the surface that requires coating.
Coating Parameters:
- Coating thickness: 0.1 to 2.0 (or more) mm
- Porosity: 2-8%
- Adhesion: 35-45 Mpa
Coating Materials:
- Pure metals and metal alloys
A mixture of oxygen and kerosene (HVOF liquid fuel), oxygen and propane/ethylene (HVOF gas fuel), or oxygen and a propane–propylene or propane-natural gas mix (HVAF) burns continuously
There are several types of plasma spraying. We use the Air Plasma Spraying (APS) technique. The nozzle of the burner consists of a tungsten cathode and copper anode.
The material in the form of wire or powder enters the ignited mixed gas (oxy-acetylene, propane-butane, propylene) where it is propelled towards the surface, substrate material which is being coated.
Equipped with machining centre and tools for machining and milling of applied metal, ceramic, and ceramic-metal coatings.
We provide blasting for coated surfaces of components in accordance with relevant and required standards neccessary for preparation of surfaces before Thermal Spray applications.
