How do you polish PVD coating? 5 Essential Steps to Perfect Finish

Polishing PVD coating involves maintaining the original surface texture of the substrate before the coating process.

How do you polish PVD coating? 5 Essential Steps to Perfect Finish

How do you polish PVD coating? 5 Essential Steps to Perfect Finish

1. Preparation of the Substrate

Before applying PVD coating, the substrate must be thoroughly cleaned to remove any contaminants that could affect the adhesion of the coating.

This cleaning process typically involves ultrasonic cleaning, rinsing, and drying.

If the substrate does not have a polished surface, it must be polished before the PVD coating process.

This is because PVD coatings do not alter the surface roughness; they merely replicate it.

2. Application of PVD Coating

PVD coatings are applied in a high vacuum environment where the metal is vaporized and combined with a reaction gas.

This process results in a thin film coating that adheres well to the substrate.

The PVD coating process itself does not involve any additional polishing steps.

Instead, it relies on the surface finish of the substrate to determine the final appearance of the coating.

3. Post-Coating Maintenance

To maintain the polished appearance of PVD coatings, it is important to use appropriate cleaning methods.

PVD coated products should be cleaned with soft cloths, water, and mild soap.

Harsh chemicals or abrasive materials should be avoided as they can damage the coating.

4. Considerations for Surface Imperfections

If the substrate has surface imperfections, these will remain visible after the PVD coating is applied.

To mask such imperfections, a polymer powder coating can be used as a pretreatment to provide a smoother surface before the PVD coating is applied.

5. Benefits of PVD Coating

PVD coatings offer very good adhesion to the substrate, maintain dimensional accuracy, and do not affect the microstructure when suitable materials are selected.

They can also be combined with friction-reducing layers and can be tailored to have variable layer structures, enhancing their functionality and aesthetic appeal.
