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.These two types are similar in profile, but their composition makes them different. PVD uses a vapor process to coat products; its chemical makeup consists of titanium nitrate. While DLC is also a vapor, it uses blasted carbon for the coating material. DLC has the upper hand in creating a more robust surface finish.In the end, choosing between PVD and DLC depends on your application needs and budget. DLC will maximize hardness and longevity, while PVD focuses more on decorative custom looks and corrosion resistance – both at excellent value.

What is the difference between Apple DLC and PVD : DLC (Diamond-Like Carbon) coating is known to offer superior scratch resistance and durability compared to PVD (Physical Vapour Deposition) due to its unique carbon-based structure. It generally provides a higher level of hardness, protecting your watch from daily knocks and scuffs.

How long will PVD last

about six months

The symptoms of PVD will change over time and usually settle down over about six months. Occasionally, the floaters caused by the PVD can last for a year or longer.

Does PVD coating wear off : The wear and tear typically seen in everyday use can gradually wear down PVD coatings, affecting their longevity. Regular contact with hard surfaces, friction, and impacts can eventually lead to visible wear. However, this process is usually slow, and the coating remains intact for many years with normal usage.

Standard Use: For typical daily wear, PVD coatings can last between 1 to 3 years before showing signs of wear. Gentle Use: With careful maintenance and infrequent exposure to harsh conditions, the coating may last upwards of 5 years.

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.

Is DLC a good coating

DLC coatings shows very interesting advantages : Good transparency in the IR (8-12µm) with a transmission better than 88% Act as a Anti-Reflective coating. Very hard protection layer, anti-scratch.DLC coatings are often used to prevent wear due to their excellent tribological properties. DLC is very resistant to abrasive and adhesive wear making it suitable for use in applications that experience extreme contact pressure, both in rolling and sliding contact.The Advantages of PVD Coating

Once applied, the coating is nearly impossible to remove, and won't wear off on its own. Additional benefits include: Clean, polished appearance when applied over a polished surface. Uniform, matte appearance when applied over a matte surface.

With PVD, there's often an increase in specks or shadows of gray or black in your vision. It may also make you see flashes of light, usually at the side of your vision. PVD may evolve over time as the gel completely separates from the retina. Your floaters may change size and shape over four to six weeks.

Does PVD scratch off : Again i wouldn't recommend it but just to to support the argument again that the coatings are very durable it's not like it would wipe off with a with a polishing compound.

Can you shower with PVD coating : Our pieces are crafted from resilient stainless steel and fortified by a 10x stronger coating process named PVD (Physical Vapour Deposition) to make our jewelry your lifetime companion. Our pieces endure sweat, showers, and beach days without losing its color.

Will PVD rust

DLC and PVD coating is the best option for knives because they are rust protection with high abrasive and heat resistance, but should not be thought of as making the steel completely rust proof.

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.One approach to PVD coating removal is through mechanical methods. Abrasive techniques such as grinding or sanding can gradually wear away the coating, but these methods often require careful control to avoid damaging the underlying substrate.

What is the disadvantage of DLC : Disadvantages of DLC

DLC is expensive and it is argued that it is not fair, having to pay to progress in a game that you have already purchased. Pressure from young gamers on their parents to buy DLC is immense. Children are easily led by clever marketing strategies.
