Machining
Equipped with machining centre and tools for machining and milling of applied metal, ceramic, and ceramic-metal coatings.
Thermal Spray Coatings require special surface treatment and tools for machining, such as diamond abrasives. We can provide surface Ra up to 0,04µM.
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.
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
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.
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.
