Physical Vapor Deposition (PVD) is our most commonly used vacuum chamber coating process. The part to be coated is placed in a vacuum chamber. The solid metal material used as the coating is evaporated under vacuum. Atoms from the vaporized metal travel at nearly the speed of light and become embedded in the surface of the part in the vacuum chamber. To ensure the correct areas of the object are coated, the parts are carefully positioned and rotated during the PVD process.
PVD coatings don’t add another layer to an object, which can chip or crack over time (think old paint). It is impregnating objects.
