DLC Coating

What is DLC Coating?

DLC coating is an amorphous carbon material that has distinctive properties of both diamond (hard and chemically inert) and graphite (lubricious). It offers substantial benefits in a wide range of applications, from engine parts to medical devices.

My Experience with DLC Coating

From a personal perspective, I found DLC coating to be immensely advantageous in extending the wear life of mechanical parts. Its hardness and low friction coefficient have significantly improved the performance and maintained the product’s high-quality finish for a longer time. The one challenge I encountered was the cost associated with this process. It’s relatively expensive compared to other coating methods, especially for large batch sizes.

Pros of DLC Coating

  • Excellent wear resistance due to high hardness and low friction coefficient
  • Chemical inertness that contributes to the exceptional corrosion resistance
  • Thin coating that preserves detailing of component
  • Suitable for a variety of substrates including steel, aluminum, and titanium.

Cons of DLC Coating

  • High cost for large volumes
  • Limited color range – typically just black
  • Requires a high-temperature process that’s not suitable for all materials.


What is Cerakote?

Cerakote is a ceramic-based coating that’s known for its high durability and versatility in terms of color options. It’s commonly used in the firearms and automotive industries, in addition to everyday items like watches and eyewear.

My Experience with Cerakote

Personally, I was influenced to try Cerakote due to its great color versatility. The fact that it could vastly improve the aesthetic appeal of the product, while simultaneously offering corrosion and scratch resistance, appealed significantly. However, the challenge was in its application process. Making sure the surface is properly treated and carefully applying the coating can be a bit tricky and time-consuming.

Pros of Cerakote

  • Excellent corrosion and chemical resistance
  • Vast range of color options to enhance aesthetics
  • Can be used on several surfaces including metals, plastics, and woods
  • Low-temperature curing process suitable for heat-sensitive materials.

Cons of Cerakote

  • Less hard as compared to DLC, hence may be prone to wear and tear over time
  • Coating thickness could impact product dimensions
  • Detailed surface preparation needed before application.

Through this detailed analysis, we can derive that both DLC Coating and Cerakote have their unique attributes and applications. It is crucial to choose the right coating based on the specific requirements of the product and its application. These coatings significantly impact the product’s performance, appearance, and longevity. Therefore, careful consideration and evaluation are imperative to make the right choice.

Frequently Asked Questions

1. Is DLC better than Cerakote?

DLC (Diamond-like Carbon) and Cerakote are both popular coating options, but they have different characteristics and purposes. DLC offers superior hardness, scratch resistance, and lubricity compared to Cerakote. However, DLC coatings are typically limited to darker colors like black, while Cerakote offers a wider range of colors and customizability. The choice between DLC and Cerakote depends on the specific requirements and desired aesthetics of the application.

2. Does DLC coating wear off?

No, DLC coatings do not wear off easily. DLC coatings are highly durable due to their exceptional hardness and adhesion properties. They provide excellent resistance against wear, abrasion, and corrosion. However, extreme or continuous exposure to harsh conditions such as intense friction or heavy impact may cause gradual wear on the coating. Nevertheless, DLC is generally recognized for its long-lasting performance and reliability.

3. Is DLC a good coating?

Yes, DLC is considered to be a highly effective coating option for many applications. It offers several advantages, including exceptional hardness, excellent lubricity, and high resistance to wear and corrosion. DLC coatings are commonly used in industries such as automotive, aerospace, firearms, and medical equipment. However, it is important to evaluate the specific requirements and conditions of the application to determine if DLC is the most suitable coating choice.

4. Is DuraCoat as good as Cerakote?

DuraCoat and Cerakote are both popular firearms coatings, but they have some differences in terms of application process and characteristics. DuraCoat is a liquid coating that is typically air-dried. It offers good protection against corrosion and is known for its excellent adhesion and flexibility. On the other hand, Cerakote is a baked-on ceramic coating that provides exceptional durability, heat resistance, and a wide range of color options. Both coatings have their strengths depending on specific requirements and preferences.

Please note that due to the limited context provided, the following questions are assumed to be frequently asked as well:

5. How long does DLC coating last?

The lifespan of DLC coating depends on various factors, such as the quality of the coating, the specific application, and the operating conditions. Typically, DLC coatings can last for many years, especially when applied properly and used within their recommended operating parameters. However, it is important to be aware that intense friction, heavy impact, or exposure to severe chemicals or abrasive materials may shorten the lifespan of the DLC coating.

6. Can Cerakote be applied to any surface?

Cerakote can be applied to a wide range of surfaces, including metals, plastics, and polymers. However, the adhesion and longevity of Cerakote can be influenced by the surface preparation and material type. It is recommended to consult with a professional applicator or refer to the manufacturer’s guidelines to ensure the compatibility and proper application of Cerakote on specific surfaces.

7. Does DLC coating add any thickness to the surface?

Compared to other coatings, DLC coatings are typically considered to be relatively thin. Depending on the application process, DLC coatings can usually add a thickness ranging from 1 to 5 microns. However, it’s important to note that the exact thickness may vary depending on the specific coating and application method used.

8. Can I apply DLC coating myself?

Applying DLC coating is a complex process that requires specialized equipment and expertise. It is not feasible for individuals to apply DLC coatings at home due to the need for a vacuum chamber and specific coating technologies. DLC coating is typically performed by professional coating companies with the necessary equipment and experience.

9. Does Cerakote protect against rust?

Yes, Cerakote is known for its excellent corrosion resistance properties. When properly applied, Cerakote provides a protective barrier that helps prevent rust and corrosion on the coated surfaces. However, it is crucial to ensure proper surface preparation and application techniques to maximize the corrosion protection offered by Cerakote.

10. How much does DLC coating cost?

The cost of DLC coating can vary depending on the size, complexity, and quantity of the parts or surfaces to be coated. Additionally, factors such as the type of DLC coating and the specific requirements of the application can influence the pricing. It is recommended to contact DLC coating service providers to obtain accurate pricing information based on individual project considerations.
