Introduction

Physical vapor deposition (PVD) is a technology where a material is evaporated and condensed to form a thin film coating over an object (substrate). With a wide range of coating materials and thicknesses, PVD can be customized to applications and the coatings can be optimized for various characteristics, such as decorative, optical, electrical, and mechanical properties.

PVD is used for depositing decorative films on watch casings, jewelry and furniture, as well as for functional films for moulds and dies, cutting tools, and low-friction machine parts. The process delivers a high pass rate and good quality, while also being environmentally friendly.

PVD has been used to successfully deposit a decorative thin film on SUS and Ti substrates, while functional films such as diamond-like carbon (DLC) film can be prepared and applied to mass production processes such as making gear parts, providing improved wear resistance.
