Powder coating, on the other hand, is a finishing process where a powder material is sprayed onto a surface and then heated to form a protective layer. The powder used in this process can be made of a variety of materials, including polyurethane, polyester, epoxy, and acrylics. Powder coating is favoured for its durability and resistance to fading, chipping, and scratching. It's commonly applied to appliances, automotive parts, bicycles, and outdoor furniture.

pvd工艺

Physical Vapour Deposition (PVD) is a process that involves the transfer of a material at a vapour level onto a substrate's surface. This can be done through various methods, but typically it involves vaporising a solid metal to a plasma of atoms or molecules and depositing them on the desired object. The result is a thin, hard, and very durable finish. PVD coatings are often used for decorative finishes on watches, medical devices, automotive trim, and high-end kitchen and bathroom fixtures.

PVD coatings are typically thinner than powder coatings and offer a higher level of abrasion and corrosion resistance. This makes them suitable for high-wear items. They also provide a range of colours with a metallic sheen, which powder coatings can struggle to match, especially in terms of brightness and reflectivity.

At LIPKA, we've embraced the superiority of PVD coating by offering an exclusive range of floor drains. Our golden and copper-coloured options, applied to 304-grade stainless steel drains, not only ensure longevity but also add a touch of luxury to any space. These finishes offer the practical benefits of PVD coatings, including their waterproof nature and corrosion resistance, while also providing an aesthetically pleasing look that is sure to complement the sophisticated design of modern homes and commercial spaces.

PVD coatings are inherently waterproof due to the nature of the bonding process at a molecular level, creating a seamless finish that is impermeable to water.

The term "better" is relative to the application. PVD coatings are often seen as superior in terms of durability and resistance to wear, tarnishing, and corrosion.

Yes, steel can be PVD-coated. In fact, PVD coating is often applied to stainless steel to enhance its appearance and increase its resistance to wear and corrosion.

Powder coatings, while they may not provide the same level of durability as PVD, are more cost-effective for larger items and are available in a wider range of textures and finishes. They are also known for their environmental benefits, as they don't involve the use of solvents and usually produce less waste.

The key differences between PVD coating and powder coating are in their application processes, the properties they impart to the coated item, and the environments they are best suited for.

In conclusion, both PVD and powder coatings have their place in the world of surface treatments. The choice between the two will depend on the specific requirements of the job at hand. Whether you seek the rugged endurance of PVD or the versatile finishes of powder coating, both processes offer solutions to keep surfaces looking great and functioning well for years to come.
