Thermal Plasma and HVOF Spray Coatings

Thermal Spray

Used in the aerospace, automotive, power generation and oil and gas industries, 榴莲视频官网入口’s thermal coatings include plasma, flame, arc spray and HVOF coating (High Velocity Oxygen Fuel) which produce a cost effective and high performing finish that protects metal components from heat, wear, corrosion, fatigue and oxidation. HVOF (High Velocity Oxygen Fuel) Coatings are a viable alternative for hard chrome plating.

Our thermal coatings can repair damaged and worn components – such as gas and steam turbines – to original specification.

Benefits of HVOF thermal spray coatings

There are a number of benefits in using thermal coating technology, and on-site spraying services, over more traditional coating methods and these include:

  • Versatility in the choice of metal coatings 鈥 options include metals, alloys, ceramics and carbides among others.
  • Component protection against wear, corrosion, fatigue, oxidation and high temperatures depending on the coating used in the process.
  • Accurately controlled temperature of the bulk substrate to 150掳C or less avoiding any detrimental effects of heat on the material properties.
  • Coating聽thickness聽easily controlled, meaning the process can even be used to restore the dimensions of a worn part or incorrectly machined component.
  • Complex shapes can be coated as the robotic parts allow for uniform coating of multifaceted parts.
  • Excellent bond strength which聽can withstand extreme mechanical loads and severe wear situations.

The process

Splat layers Stages Powder particles (typically 1 to 50 microns) are heated to a molten or semi-molten state and are propelled at high velocity, using kinetic energy formed from a gas stream, onto the surface and forms a splat.

This splat then contracts as it cools forming a bond with the surface.

Each splat deposited builds up in layers to the required thickness and density.
