Physical Vacuum Deposition (PVD) in Watchmaking: The "Tech Outer Layer" for Precision Timepieces When you touch the smooth matte black case of the watch, admire the warm and lustrous appearance of the rose gold strap under the light, or marvel at the intact appearance of the diving watch in the deep ...

Dual-Layer Vacuum Coating: Color Plating + Transparent Anti-Fingerprint & Anti-Oxidation Layers on Silver, Copper, and Stainless Steel Jewelry 1. Introduction In the global jewelry market, consumers increasingly pursue products that balance aesthetic elegance with long-term functionality. Fingerprin...

Vacuum coating of ceramic mugs is a process in which metal or compound targets are deposited onto the surface of the mug body through physical vapor deposition (PVD) technology in a vacuum environment, forming decorative (such as metallic luster, gradient color) or functional (such as wear-resistant...

Mastering Multi-Arc Ion Plasma PVD Coating: Gas Settings, Colors & Complete Process In the dynamic field of advanced surface engineering, multi-arc ion plasma PVD (Physical Vapor Deposition) vacuum coating technology has emerged as a game-changer—delivering both exceptional functional performance ...

Optical coating, as a core technology for enhancing the performance of optical components, is widely used in laser equipment, imaging systems, photovoltaic devices and other fields. Its quality directly determines key indicators of optical systems such as transmittance, reflectance and environmental ...

The Art of Colorful Stainless Steel: How Vacuum Coating Creates Gold, Rose Gold & Beyond Stainless steel is a staple in modern manufacturing, prized for its strength, corrosion resistance, and versatility. But what if this utilitarian material could be transformed into a canvas of rich hues—gold, ...

In the clear display of smartphone screens, in the images of distant galaxies captured by astronomical telescopes, and in the precise operation rooms of laser surgeries, an "invisible technology" is playing a core role - this is optical coating. It is an ultra-thin material layer deposited on the ...

I. Core Principle Overview 1. E-Beam Evaporation Utilizes high-energy electron beams to bombard target materials, converting kinetic energy into thermal energy to melt or sublimate the target. Gaseous atoms condense on the substrate surface to form thin films. A "thermal evaporation deposition" ...

Invisible contributor Throughout the development of photography and imaging technology, optical coatings have always played the role of "invisible heroes". From the single lenses of early film cameras to the complex optical modules of today's professional single-lens reflex cameras, mirrorless ...
