In today's interior architecture and design landscape, it's increasingly common to encounter projects where architects and interior designers delve into the world of SPA and wellness center showers. Colors, special finishes, including metallic ones such as bronze, gold, copper, brass, and others, as well as solid painted hues, are explored. When it comes to incorporating metallic colors, the durability of the layer responsible for these striking finishes must withstand harsh environments, such as those involving thermal water or chlorine.
Revealing the Technology Behind Metallic Finishes: PVD
What technology drives the creation of these captivating metallic finishes? The answer lies in PVD (Physical Vapor Deposition), an advanced process commonly used for such finishes.
Without delving too deeply into technical details, it's beneficial to understand the advantages offered by PVD compared to existing methods. PVD works by vaporizing metals (such as Zirconium, Titanium, among others) inside a vacuum chamber, which is infused with a specific gas.
The combination of various metals and gases, along with variations in pressure and temperature during the vaporization process, generates the diverse spectrum of colors and surfaces characteristic of PVD. The elements deposited on surfaces primarily include carbides and nitrides, known for their exceptional mechanical and chemical properties.
Understanding the Advantages of PVD
Diversity of Colors: PVD enables a wide range of colors, from basic shades (yellow, gray, brown, black) to more nuanced tones like gold, brass, bronze, steel, nickel, and beyond.
Exceptional Durability: PVD-coated surfaces offer remarkable hardness, often doubling that of chrome plating.
Superior Chemical Resistance: PVD surfaces demonstrate outstanding resistance to chemicals, ensuring integrity against common cleaning agents.
Environmental Responsibility: The PVD process has zero environmental impact, producing no harmful waste: a more eco-friendly alternative.
In summary, PVD emerges as a formidable alternative to traditional coating methods for brass, steel, and aluminum alloys, offering significant advantages particularly suited to specialized contexts such as hotels, spas, thermal baths, pools, and outdoor installations in general.
