Surface preparation is key to the success of any thermal spraying process. The steps involved should be closely monitored throughout to ensure high-quality control and correct application.
Thermal spraying is a coating process that uses the pressure of a high-heat gas to spray molten particles onto a substrate. It is used in a wide variety of industries and applications.
How the surface is prepared
Preparing the substrate correctly before the thermal spraying and coating process ensures excellent results, so let’s look at the steps involved:
- Degreasing allows any contaminants to be removed from the surface prior to treatment. Failure to do so may result in low-quality bonding with the substrate.
- Masking is then required to protect the areas of the substrate that do not require coating.
- To ensure maximum adhesion, the surface needs to be activated. This can be achieved through grit blasting, water-jet stripping, laser ablation, or mechanical roughening.
- The correct surface profile is needed to ensure optimum adherence.
