Physical Vapor Deposition (PVD) is a general term used to describe several thin-film coating processes. Evaporation, sputter deposition, electron-beam evaporation, ion beam, pulsed laser, and cathodic arc are examples of PVD processes, with cathodic arc deposition and sputter coating playing key roles in decorative and functional industrial applications. Below, we compare both technologies.
PVD coating basics: what cathodic arc deposition and magnetron sputtering have in common
- Both use a solid source (called a target) and different inert and reactive gases to deposit thin films.
- Both are performed in a vacuum and make use of ionized species (plasma) to remove material from the target.
- Both can produce thin-film coatings used in decorative and/or functional applications.
- Nitrides, carbides, oxides, and more complex compounds are possible by both processes.
Comparison: cathodic arc vs. sputter coating (hint: The “better” method depends on your coating requirements)
Need something different? Vapor Technologies has 2 new solutions:
1. RAAMS® Technology: More than traditional magnetron sputtering
When a functional application requires a thick coating with superior mechanical properties, RAAMS technology offers a unique solution that other sputter coaters can’t duplicate. Excellent for coating tooling and high-performance engine components, RAAMS technology is an industrial-grade solution for lower ionization rates than conventional sputter coating machines. RAAMS technology uses an independent electron source to exponentially increase ionization of gas and metal ions inside the deposition chamber, boosting deposition rates, shortening coating times, and improving PVD thin-film coating density, hardness, and wear resistance. Our Cadence™ machine uses RAAMS technology to deposit films tens of microns thick.
2. Dual-method coatings: Cathodic arc deposition + sputtering = unique specialty coatings
Sometimes, applications require unique specialty coatings a sputter coater or cathodic arc physical vapor deposition system cannot provide on their own. To tackle those hard to achieve hybrid coatings, use the VaporTech VT-1500i system with cathodic arc PVD and sputter coating machine capabilities in the same machine.
