Product Introduction
Product Description
Multi-arc chromium cathode targets are high-purity chromium-based deposition materials used in multi-arc ion plating and physical vapor deposition (PVD) coating systems.
The multi-arc deposition process generates high-energy electric arcs between the cathode target and anode, causing chromium atoms to be ionized and deposited onto the substrate surface, forming high-performance thin films.
Chromium coatings are widely used due to their high hardness, excellent wear resistance, strong corrosion resistance, and decorative metallic appearance.
Manufacturing Process
Chromium targets are manufactured using advanced powder metallurgy and Hot Isostatic Pressing (HIP) technology, ensuring:
High density
Uniform microstructure
Stable sputtering performance
Extended service life
Available shapes include:
Rectangular targets
Arc targets
Annular targets
Tube targets with large aspect ratios
