Frequently Asked Questions
Thermal spray processes are mainly classified into five main categories. They are:
• Wire Flame spraying
• Combustion Powder Flame Spraying
• High velocity oxy fuel (HVOF) spraying
• Electric Wire Arc spraying
• Plasma spraying
Thermal spray feedstocks can take several forms which are suited to various materials such as:
• Powder – plastic, metal, composite, ceramic
• Wire – metal, composite
• Rods – ceramic
• Liquid
• Thermal barrier coatings
• Corrosion Resistant (Anticorrosion) coatings.
• Abradable
• Reclamation of worn components.
• Art – glass colouring, bronze application.
• Electronic applications
• It is a fast coating deposition process.
• Wide variety of materials can be used to make a coating. Virtually any material that melts without decomposing can be used.
• Most of the thermal spray processes apply a coating to a substrate without significantly heating it. Thus, materials with very high melting points can be applied to finally machined, fully heat-treated parts without changing the properties of the part and without thermal distortion of the part.
• Ability to strip and recoat worn or damaged coatings without changing the properties or dimensions of the part.
A molten particle or a particle able to deform plastically is transported at high speeds within a heat source towards a surface upon which deposition occurs. The droplet or particle undergoes spreading and may create a chemical bond with the underlying surface. With materials that are not able to produce a chemical bond, the substrate is roughened to create a mechanical bond. Each droplet or particle impacts a roughened surface and mechanically interlocks with the asperities on the underlying surface.

Below is a list of available Metal Coat Thermal Spray systems:
• Combustion Wire – Oxy/Acetylene or Oxy/Propane fuelled torch that uses wire form material.
• Combustion Powder – Oxy/Acetylene or Oxy/Propane fuelled torch that uses powder form material.
• Electric Wire Arc – A dual wire system using electricity to melt wire form material.
• HVOF – High Velocity Oxy Fuel delivers powder form material at supersonic speeds.
