Details of our DLC Coating Service Process
Mekalite utilizes internationally advanced Physical Vapor Deposition (PVD) and Plasma Enhanced Chemical Vapor Deposition (PECVD) processes to achieve Diamond-Like-Carbon (DLC) coatings with high uniformity and excellent performance. Our coating process covers every step from surface pretreatment, optimization of deposition parameters to final inspection to ensure a stable, robust and dense coating.
- Surface pre-treatment: Thorough cleaning and activation of the substrate material ensures adhesion between the coating and the substrate and reduces the risk of flaking.
- Precise control of parameters: Depending on the material and application requirements, parameters such as vacuum, gas ratio, deposition time and temperature are adjusted to obtain the best coating performance.
- Multi-layer structure design: Multi-layer or gradient structure design can be used to further enhance abrasion resistance and protection to meet the needs of extreme use environments.
- Comprehensive monitoring and quality control: Key indicators in the process are monitored online and all finished products are rigorously tested for thickness, adhesion and performance.

What are the functions of DLC coating service?
DLC (Diamond-Like Carbon) coating services provide a range of valuable functions for a variety of components and surfaces. The primary function is to significantly improve wear resistance, protecting parts from abrasion and extending their service life. It also creates low-friction surfaces that reduce energy loss and minimize heat generation between moving parts.
DLC coatings provide excellent corrosion protection and act as a barrier against moisture and chemical attack. Coatings increase surface hardness, making parts more durable and more resistant to scratches or impacts. In addition, DLC coatings are chemically inert, biocompatible (for medical applications), and enhance the aesthetics of the product due to their bright, uniform finish. In short, DLC coating services help to improve the performance, reliability and lifetime of mechanical, electronic, automotive, medical and industrial components.
Key Properties of DLC Coatings
DLC coatings stand out for their exceptional physical properties. Here are the primary technical specifications:
Property
Value
Hardness
15-30 GPa (2000-5000 HV)
Coefficient of Friction
0.1-0.25 (dry), <0.1 (lubricated)
Coating Thickness
1-5 microns
Deposition Temperature
~170-200°C
Max Service Temperature
~350°C
These attributes make DLC coatings ideal for applications requiring high wear resistance and low friction, such as engine components, cutting tools, and medical implants.
DLC vs. Traditional Coatings
DLC coatings outperform many traditional PVD coatings. Here’s a comparison with TiN and CrN:
Coating | Hardness (HV) | Coefficient of Friction | Max Temperature |
|---|---|---|---|
DLC | 2000-5000 | 0.1-0.25 | 350°C |
TiN | 2300 | 0.4-0.6 | 600°C |
CrN | 1800 | 0.3-0.5 | 700°C |
DLC’s friction coefficient is 200-500% lower than TiN and CrN, making it ideal for low-friction, wear-resistant applications, while its low-temperature deposition suits a wider range of substrates.
Deposition Methods
DLC coatings are deposited using advanced vacuum techniques such as Physical Vapor Deposition (PVD) or Plasma Enhanced Chemical Vapor Deposition (PECVD). These methods ensure strong substrate bonding, uniform coating distribution and long-lasting surface properties.
