Spare Parts Repair by Metal Spray (HVOF) or Welding
The basic processes of thermal spray – Cold Work
Processes (no deflection of the work piece) – consist of melting the material to be
Sprayed to the plastic stage & atomizing it to a fine
Stream of particles & then propelling the fine
Particles at a great velocity to the substrate or base
Material to form coating layer to protect the Component
Surfaces from corrosion & wear.
