What is AlTiN Coating?
AlTiN coating (Aluminum Titanium Nitride) is a type of Physical Vapor Deposition (PVD) coating that enhances the surface properties of tools and components. These PVD Coating Services ensure a uniform coating layer with excellent adhesion and performance.
It is composed of aluminum, titanium, and nitrogen, forming a protective layer that improves:
- Hardness
- Thermal stability
- Oxidation resistance
Moreover, this coating is known for forming a protective aluminum oxide layer at high temperatures, which significantly improves performance.
