The hardness of a quality DLC coating should rate around 3,000 HV which would equate to an approx- imate rating of 80–98 Rockwell. The high hardness of the DLC coating allows the component to become more resistant to scratches and scrapes that occasionally occur during installation or operation.While the hardness and amorphous nature of a DLC coating is an attractive property, it also makes it an unforgiving coating when it comes to residual stress within the coating and the substrate. Rather than deform under residual stress, a DLC coating tends to delaminate from the substrate.Extreme scratch resistance

Whether on the glass or the case. Stainless steel can also be scratch-prone when exposed to other harder metals. The harder the case material, the more scratch-resistant the watch. For this reason, DLC-coated housings are extremely hardened and thus more scratch-resistant than PVD material.

What are the benefits of DLC coating : DLC coatings reduce friction and wear by providing a smooth, low-friction surface that reduces the resistance to motion between two surfaces in contact. The coating's unique structure and composition provide excellent lubricity, making it more resistant to wear caused by friction.

Does DLC wear off

The coating adheres to the surface and does not wear away as rapidly as a PVD-type coating. That's not to suggest you won't be able to harm it, so don't go out of your way to try.

Is DLC or Cerakote better : Cerakote's aerospace and military-grade coatings require no oiling and offer 330 times the corrosion protection of PVD/DLC while exceeding military standards by over 40 times.

One of the most important benefits of DLC coating is the corrosion resistance; therefore, you can use DLC-coated tools in highly corrosive environments without the rust or stains formation. The corrosion resistance performance of Diamond-Like Carbon is attributed to its physical and chemical properties.

From what I've gathered on the forums and various sites, DLC is generally tougher and more resistant. There are many stories to be found about a PVD job that has begun to wear around the edges in under a year. That said, there are lots of businesses that do these coatings, and they are not created equally.

Is cerakote better than DLC

Cerakote ceramic coatings are a premium upgrade and an excellent alternative to PVD (Physical Vapor Deposition), Ionbond, and DLC coating (diamond-like carbon coating).DLC coating costs approximately $20 per part when using a coating service.DLC coatings represent the ideal solution for many applications such as tribological applications and many more. One of the most important benefits of DLC coating is the corrosion resistance; therefore, you can use DLC-coated tools in highly corrosive environments without the rust or stains formation.

One disadvantage of Cerakote is that, while it helps protect against rust, it's not rustproof — no coating is. When we sharpen our blades or laser our logo, we expose the steel to oxygen, creating a place where rust can start. Another disadvantage is that Cerakote wears less gracefully than Parkerizing.

Is DLC coating food safe : Beyond elevating the look of your blade with its characteristic black cloak, our diamond-like carbon coating is also food-safe.

How long will Cerakote last

For guaranteed 12 month shelf life please follow storing recommendations below. We do NOT recommend storing Cerakote® in a working refrigerator. Excessive moisture in a refrigerator will compromise Cerakote® products if not properly sealed.

With a commitment to excellence and a dedication to innovation, Cerakote is the trusted choice for the defense industry. Our coatings are relied upon by military and defense organizations worldwide.And while it's not the most popular opinion, I do love the look of a clean, un-worn black coating. That's why DLC coatings are my favorite; they wear very slowly. But if you're the kind of person who likes to see their knife beat up, then a powder coat or a ceramic coat might be the ticket!
