Thermal Spraying

Thermal Metal Spraying In Situ

Metalock Engineering is a leading specialist in Thermal Spraying and applying Surface Treatments to metal components.

Continuous development of new Surface Coating Processes means we meet industry’s voracious appetite for new products and give engineers ways to repair and protect a wide range of mechanical engineering equipment – for longer life, lower manufacturing costs and cost-effective repair instead of expensive replacement.

Surface Treatments to Metal Components

Thermal Spray Coating involves heating material (in powder or wire form) until it is a molten state, then propel it with gas or air to deposit a layer on a receiving component. This process can be repeated many times allowing us to build several layers to precise specifications.

Highly-trained Specialists

Common applications for thermal spraying and surface treatments include these:

  • Repair & Reconditioning
  • Anti-corrosion coatings
  • Heat shielding
  • Erosion prevention
  • Insulation

Depending on your requirements, our highly-trained specialists will work in the workshop or on site – spraying a huge variety of different materials. If you can melt it you can spray it:

  • Steel 
  • Tungsten carbide
  • Chrome carbide
  • Ceramics
  • Plastic composite

How can we save you time and money, and build your reputation with Thermal Spraying and Surface Treatment?

High-Quality Results

You can count on us for the highest quality Thermal Spraying and consistently high-specification results on all types of components with a wide range of materials. These may be single elements, but are more usually alloys or composites with unique physical properties that are only achievable with Thermal Spraying using one of these techniques:

  • High-Velocity Oxygen Fuel (HVOF)
  • Flame spraying
  • Arc spraying
  • Plasma spraying

Thermal Spraying of Railway Axles

Malmö, Sweden

Railway axles, Denmark

Renovate railway axles to original condition and save them from being scrapped.

Metalock developed a solution that made it possible to have the axles mounted on the gearbox during the spraying process.

Thermal spraying build up the diameter and then the surface was machined and polished to see the tolerance 0.029mm.

Saving 998 railway axles from being scrapped. Longer durability than original, while making it possible to extend the life span by the repeated rework.

The tolerance was measured up to 0.01 - 0.02mm, well under specified requirements.
