Plasma gases (argon, hydrogen) passed through a powerful
electric arc in the spray gun are ionised to form a plasma flame with a core
temperature of 10000 °C. Thermal powders directed into this flame are sprayed
as a melt.
The extremely high temperature plasma core flame easily
melts hard-to-melt thermal powders such as ceramics and bonds them to the base
material with a strong bond.
During the application, the temperature of the workpiece is
controlled to prevent any tension that may occur in the coating.
Thermal powders with different properties are used in plasma
spraying applications.
Plasma spray coatings are widely used in industrial
processes. It is successfully applied in wear problems, prevention of high
temperature corrosion, acidic and basic environments, thermal barrier
formation.
Pump parts, shafts and sleeves, mechanical seals, pump
pistons, textile machinery parts, yarn guides, drawing rollers, drawing
rollers, tension rolls, grooved rollers, guide rollers, printing rollers, steel
rollers, paper rolls are the application areas.
