Product Description
Naixin DLC Black Titanium PVD Coating is a high-performance surface treatment specifically designed for aluminum alloy components. This advanced coating combines Diamond-Like Carbon (DLC) technology with the sleek aesthetics of black titanium, applied through high-precision Physical Vapor Deposition (PVD). Optimized for aluminum substrates, it delivers exceptional surface hardness, wear resistance, and corrosion protection. The diamond-like carbon structure significantly enhances the mechanical durability of aluminum parts, while the rich black metallic finish adds both functional value and premium visual appeal. With strong adhesion and thermal stability on aluminum, this coating is ideal for automotive, aerospace, electronics, precision tooling, and high-end consumer applications requiring reliable, long-lasting surface performance.

Technical Introduction
The filtered arc vacuum coating technology (DCVA) uses arc discharge to ionize the target material under vacuum conditions, generating ions, electrons and particles. The particles are filtered through a magnetic field to clean them up, and 100% pure ions are deposited on the surface of the workpiece to form a mirror coating. The maximum coating area is 300 mm * 300 mm.
