Huasheng DLC Coating: Advanced Surfaces for Precision Manufacturing

Huasheng Nanotechnology is a leading expert in DLC coating technology, offering high-performance solutions for precision components in robotics, automotive, and semiconductor industries. With over ten years of experience, the company has developed an integrated coating system combining PECVD and PVD hybrid processes, achieving outstanding coating quality, adhesion, and production efficiency.

The PECVD-based process uses a closed magnetic field design to enhance plasma density by over 40%. This allows fast deposition rates above 1 μm/h while keeping temperatures below 150°C, ensuring no thermal deformation for precision parts. The coating surface is extremely smooth and free from large particle contamination.

For demanding applications, Huasheng integrates magnetron sputtering (MS), HiPIMS, and arc ion plating (AIP) technologies to enhance coating density and adhesion. The hybrid system improves coating compactness by 30% and achieves stable adhesion at HF1 grade. A Cr or Ti transition layer ensures excellent bonding with different substrates.

Huasheng’s customized DLC coatings include:

a-C:H (Hydrogenated DLC): Balances hardness (1500–2500HV) and low friction (0.05–0.1), ideal for harmonic drive components.

ta-C (Hydrogen-free DLC): Offers extreme hardness (4000–6000HV) and superior wear resistance for high-load gears.

Functional doped coatings (F-DLC, Si-DLC): Provide hydrophobic or corrosion-resistant properties for medical and semiconductor applications.

Multilayer DLC coatings: Combine high hardness, toughness, and low friction for dynamic or high-stress conditions.

Huasheng operates over 70 advanced vacuum coating systems, including the self-developed TC800 and DLC1500 models, ensuring high coating uniformity (≤3%) and automated process control.
