Coating reference
The cited data behind the Explorer. Each PVD coating below carries its typical hardness, heat limit, and friction — as ranges, because real coatings vary by process and supplier. Open any one in the PVD Coating Explorer to see the notes and sources behind every number.

Every value here is sourced and dated, and the underlying source documents are archived so each claim stays auditable. These are general process properties for understanding tradeoffs — not a specification for your application. Real selection needs a coating house with your substrate, geometry, and duty data.
