Vacuum Coating Technology (PVD)

Physical Vapor Deposition (PVD) is a vacuum-based technique depositing ultra-thin protective or decorative films by evaporating or ionizing solid materials. PVD coatings enhance hardness, adhesion, chemical resistance, and aesthetics.

• Methods: Arc evaporation, thermal evaporation, DC/MF ion bombardment, ion beam deposition, ion plating, enhanced sputtering.
• Materials: High-purity metals including titanium, chromium, zirconium, silver, gold, aluminum, copper, stainless steel.
• Advantages: Thin, durable coatings with excellent adhesion; uniform coverage on complex parts; corrosion and wear resistance; environmentally friendly; cost-effective precious metal coatings.

Sputtering Process

Sputtering uses plasma generated by voltage applied to rarefied gas to eject atoms from a target material, depositing thin films on substrates. Magnetron sputtering improves ionization efficiency with magnetic fields, enabling high deposition rates at low substrate temperatures suitable for industrial production.
