PVD Coating / Thin Film

Physical Vapor Deposition – also known as PVD Coating or Thin Film – refers to a variety of deposition techniques where solid metal is vaporized in a high vacuum environment and deposited on electrically conductive materials as a pure metal or alloy coating.

As this “line of sight” process transfers the coating material on a single atom or molecule level, it can provide extremely pure and high performance coatings which for many applications are much preferable to electroplating. PVD coating is used when the product requires thin film for a mechanical, an optical, a chemical or an electronic function.

These thin film finishes are also highly resistant to tarnishing, enabling them to be used for a wide range of applications with colors that do not fade. When applied to a base metal, a PVD coating provides hard, wear-resistant surfaces that don’t interact with the materials they cover – dramatically reducing friction and prolonging the life of the part.

This is an environmentally friendly process that can greatly reduce the amount of toxic substances to be disposed of with more conventional types of coating involving fluid precursors and chemical reactions.

Techmetals offers roughly 26 different PVD coating options – perfect for use with medical equipment and firearm production. We offer certifications for Nadcap Chemical Processing, Nadcap Coatings, ISO 9001:2015, ISO 13485:2016, AS9100D, FAA, ITAR, as well as validated processes for the medical industry.

Benefits of PVD Coating:

  • Reduction of friction
  • Improved lubricity
  • Abrasion & wear resistance
  • Improved speeds & feeds on cutting tools
  • Better release of plastic parts
  • Less galling & die polishing
  • Reduces downtime
