How Does PVD Coating Work? A Step-by-Step Surface-Finishing Guide

1. What Does “PVD Coating Work” Actually Mean?

“PVD coating works” = vacuum physics + nano-chemistry turning your substrate into:

2 500–3 500 HV hardness
0.04–0.08 friction vs. steel
1 000 °C oxidation resistance
REACH-compliant finish

All in ≤ 3 µm without dimensional change.
