All manufacturing businesses know that when a critical part breaks down, it’s not just the cost of replacing it that has an impact. Downtime has an effect on lead times, creating an even bigger problem. That’s why using thermal sprays can help to restore worn components, helping you carry on with the project.
Why components fail
It’s not often that parts suddenly fail – instead, it’s a gradual effect of corrosion, abrasion, heat, erosion or repeated stress from contact. Once a component becomes damaged, it can lead to shrinkage and uneven wear, leaks and vibration, as well as reduced output.
Protective coating
Thermal sprays mean applying a coating material at high speed to a prepared surface. It bonds mechanically to form a durable layer that can withstand extreme operating conditions. Once the coating has been applied, the surface is put back to the required profile and shape. For more information about thermal sprays, you can consult experts such as www.poeton.co.uk/surface-treatments/thermal-metal-sprays.
Types of thermal spray
Different sprays are available for different conditions, but are seen as key to help with sustainability. Remanufacturing includes surface enhancement via thermal spray.
Plasma spray is normally used for high temperature and ceramic needs, while High Velocity Oxygen Fuel coating is best for industrial parts, due to it being dense and wear-resistant. If the main aim is protection against corrosion, metalising is a good option and cold spray can help with heat-sensitive substrates, as it has minimal heat impact. Finally, PTA hardfacing and spray and fuse hardfacing are good for environments with heavy wear.
