Advantages of Thermal Spray Coatings
- Wide range of coating materials – there is a vast array of different materials which can be turned into high quality coatings via the thermal spray process. These can include; metal, alloy, ceramic, plastic and polymer and can be in the form of powder, rod or wire. The coating material can be specifically selected for each individual substrate and the job that it has to do and so a near perfect match can often be made between the two.
- Wise variety of substrate materials – as long as the material to be coated can withstand the heat of the thermal spray process then almost any material can be coated using this method. However there are also a number of specific spray coating methods which in fact use much lower temperatures and so the range of substrate materials is even further increased.
- Extends the lifespan of the substrate – a strong and efficient thermal spray coating will extend the lifespan of that substrate by providing an effective barrier against erosion, decomposition and other forms of surface damage. Thermal spraying allows much thicker coatings to be applied (often up to 10mm) in higher deposition rates than other coating methods, which provide a much more effective barrier against wear and tear.
- Reduced cost – in many cases repairing an object by applying a thermal spray coating to it is much cheaper than completely replacing it. Also thermal spray coatings tend to be much more efficient and waste less of the coating material than with other methods so are a much more viable option when more expensive coating materials are involved.
