Processes
THERMAL SPRAYING
Thermal spraying includes multiple processes defined by spray material, operation type, or energy source, as per EN ISO 14917.
These processes are complementary, not competitive, and each is suited for different applications based on their characteristics.
All thermal spray methods require two forms of energy: thermal energy (to melt/fuse the spray material) and kinetic energy (to propel particles onto the surface).
Common energy sources used include oxy-fuel-gas flames, electric arcs, and plasma jets.
Kinetic energy affects coating quality, influencing coating density, bond strength within the coating, and adhesion to the base material, and varies by process, material, and particle size.
Types (More details):
Atmospheric Plasma Spraying (APS)
The atmospheric plasma spraying process is used for protection against wear and corrosion as well as for thermal insulation, repair, and restoration.
Vacuum Plasma Spraying (VPS)
The vacuum plasma spraying process is used to process oxidation-critical materials in a vacuum atmosphere.
High velocity flame spraying (HVOF)
Wear and corrosion resistant surfaces are used to protect critical components in numerous industries.
Wire flame spraying
Wire flame spraying is used for coatings against corrosion and to restore the dimensional stability of components.
Powder flame spraying
Powder flame spraying is used for coatings against corrosion and to restore the dimensional stability of components.
Arc Spraying
Arc spraying offers excellent portability and flexibility for on-site or shop coating operations.
Plasma Spraying RSW
Spraying in a controlled atmosphere produces very pure, oxygen-free coatings.
LASER CLADDING
LASER CLADDING
Laser cladding is an additive manufacturing process that uses a laser to melt both the base material's surface and an added material (typically powder) to create a metallurgically bonded coating.
The process creates a melt pool through localized heating, with the additive material fed simultaneously and solidified by the relative motion of the cladding head.
Precise and controlled heat input results in minimal mixing and strong bonding, ensuring high-quality coatings with excellent adhesion.
The technique offers high accuracy and repeatability, reducing or eliminating the need for masking and costly post-processing steps.
It has excellent material efficiency, with powder utilization rates reaching up to 95% or more under industrial conditions.
