Vapor deposition low friction coatings can offer excellent means for dry lubrication, lower friction. Particularly in high wear applications or higher temperatures, where organic-based materials are not sustainable..
Polish your parent metal. Friction is a function of surface finish. Vapor deposition coatings are thin film, conformal, and will replicate your existing surface finish, imperfection and all.
Processes include: Chemical Vapor Deposition (CVD), Low-Pressure Chemical Vapor Deposition (LPCVD), Physical Vapor Deposition (PVD) and Plasma-Assisted Chemical Vapor Deposition (PECVD).
Though their transport mechanisms vary, all involve a work piece whose surface must be made active to accept a variety of materials, including metals, alloys, semiconductors, superconductors and polymers.
Builds begin at the atomic level and end typically between 1 and 12 micrometer in thickness.
Sharing heat treat history and alloy of metal are essential. While lower temperature processing is available today, re-tempering may be needed. Talk to our sponsors and discover how to remove risk in dimensional or surface distortion.
Will your base metal experience plastic deformation in service? Be sure your coating provider understands both your low friction needs and surface mechanics. Acting forces need to be understood if the current failure mode is unknown.
Today, advancements in thin film coating include multiple layers truly state-of-the-art. Properties such as low friction can be gained in service, without need for boundary lubricants. Whether co-evaporation or co-sputtering, these techniques allow creation of composite materials of various form, including: particle, fiber, or laminate.
Many are compatible with medical and food processing, making them preferred choices under the most abrasive conditions, where dry lubrication, low friction are key.
