If you’re evaluating a PVD coating service, start with the friction problem you’re trying to solve. List the contact surfaces, the load, and the temperature at the point of contact. That helps the provider choose a low friction coating that will stay stable in your real environment.

Ask what prep steps they use. Cleaning, surface activation, and fixturing affect adhesion and uniformity. A reliable PVD coating service should explain how they control thickness to ensure coated parts still meet fit and tolerance requirements.

Request proof, not promises. Ask for a sample report showing coating thickness and adhesion checks, then run a short pilot batch. Compare a low-friction coating against your current finish on the same machine settings. Track parts-per-tool, power draw, and surface finish.

Finally, confirm handling and packaging. Coated surfaces can scratch if parts knock together in transit. Good packaging protects the low-friction coating and prevents surprises when the batch arrives.
