Degreasing | In this step, a cleaning solution is sprayed onto the workpiece surface to eliminate any grease, oil, or contaminants. Effective degreasing is crucial for ensuring optimal coating adhesion. |
Phosphating | Phosphating involves applying a phosphate solution to the workpiece's surface through spraying. This process forms a thin, adherent phosphate layer that enhances both coating adhesion and corrosion resistance. |
Rinsing | Following each pretreatment stage, the workpiece undergoes rinsing with water to clear away any residual cleaning or pretreatment chemicals, ensuring a clean surface for the next step. |
Surface Conditioning | Some pretreatment systems incorporate a surface conditioning phase, where the workpiece is treated with abrasive media to create a textured surface. This step can significantly improve coating adhesion, particularly for specific materials. |
Drying | Prior to the coating application, drying the workpiece ensures a clean, moisture-free surface, which is essential for achieving a successful and durable coating. |
