DLC coating, which stands for Diamond-Like Carbon coating, is a process that uses Plasma-Assisted Chemical Vapor Deposition (PACVD).
The cost of DLC coating can vary significantly depending on whether you use a coating service or run your own DLC coating machine in-house.
How Expensive is DLC Coating? 5 Key Factors to Consider
1. Cost of Using a Coating Service
If you use a coating service, DLC coating costs approximately $20 per part.
This option is more suitable for low-volume coating needs.
2. Cost of Running Your Own DLC Coating Machine
If you have your own DLC coating machine, the per-part coating costs can be significantly reduced, sometimes to less than $1 per part.
3. Benefits of DLC Coating
DLC coating produces a "diamond-like" carbon film.
These films are hard, scratch-resistant, and have good barrier properties.
They are often used as protective coatings for various materials due to their high hardness and chemical resistance.
4. The PACVD Method
The PACVD method is commonly used to deposit DLC films.
This method allows for the deposition of carbon films with a wide range of optical and electrical properties.
DLC films deposited using PACVD show good adhesion to many substrates and can be deposited at relatively low temperatures.
5. Advantages of PACVD Over Other Coating Methods
One advantage of PACVD over other coating methods like Chemical Vapor Deposition (CVD) is that PACVD can be done at lower temperatures, even at room temperature.
This prevents distortion of the substrate.
PACVD also offers benefits such as chemical stability, fewer toxic byproducts, quick processing time, and high deposition rates.
DLC coating is commonly used in various industries.
For example, it can be used as an engine coating for automotive components to make them wear-resistant and reduce friction.
It can also be used as a tool coating, particularly for machining aluminum and plastic injection molds, thanks to its anti-sticking properties.
