Cathodic Arc Deposition

Cathodic Arc Deposition is a process used to apply thin, durable coatings to surfaces by creating a high-energy arc of plasma from a target material (the cathode). When the arc strikes the target, it vaporizes tiny amounts of material, which then travel through a vacuum or low-pressure environment and settle onto the object’s surface as a thin film. This method produces very strong, wear-resistant coatings often used in tools, electronics, and protective layers, offering excellent adhesion, density, and hardness due to the energetic nature of the deposition process.
