THERMAL SPRAYED COATINGS
The coating material, in powder or wire form, is melted by a heat source and propelled using a stream of gases or compressed air on to the prepared surface to form a coating.
POWDER FLAME SPRAY PROCESS
Material in powder form is melted in a flame (oxyacetylene or hydrogen) and sprayed on a prepared surface.
WIRE FLAME SPRAY PROCESS - METALLIZING
Material in wire form is melted in a flame (oxyacetylene), atomized using compressed air and
sprayed on a prepared surface.
ELECTRIC ARC WIRE SPRAY PROCESS
In arc wire spray process a pair of electrically
conductive wires are melted by means of an electric
arc, molten material is atomized by compressed air
& propelled towards the substrate to form a coating
HVOF (HIGH VELOCITY OXY-FUEL PROCESS)
Coating material in powder form is melted using oxy
-fuel flame and propelled on to the prepared surface at supersonic velocity. Coating material impinges on substrate & cool down to form coating
AIR PLASMA SPRAY PROCESS
Coating material in powder form is melted in a hot
plasma plume and propelled on to a prepared
substrate to form a coating
