The Hidden Hero of PVD Coating: Understanding Targets in Jewelry & Hardware

When you admire the golden shine of a jewelry ring or the sleek black finish of a luxury bag clasp, have you ever wondered—what makes these colors and finishes possible?

Behind the beauty lies an unsung hero: the PVD target.

 

What Is a PVD Target?

In Physical Vapor Deposition (PVD), a “target” is the raw material placed inside the coating chamber. Under high energy—through processes such as arc evaporation or magnetron sputtering—atoms from the target are ejected and deposited onto the product surface, forming a thin, decorative, and highly durable coating.

In short,   the target defines the coating.

 

Theory Behind Targets & Coatings

Reaction with Gases: When reactive gases like nitrogen, carbon, or oxygen are introduced, the metal atoms from the target combine to form nitrides, carbides, or oxides. For example:

Ti + N₂ → TiN (gold color)

Zr + N₂ → ZrN (pale gold)

Ti + C + N₂ → TiCN (gray to black)

Purity & Density: High-purity, dense targets ensure coatings with fewer defects, higher adhesion, and better corrosion resistance—critical for jewelry and hardware exposed to skin contact and daily wear.

Deposition Control: By adjusting parameters like power, pressure, and gas ratio, manufacturers can fine-tune coating thickness, hardness, and color tone.

 

Common Targets & Colors in Jewelry and Hardware

Different targets create different colors and properties:

Titanium (Ti): Classic gold, rainbow-like hues → used in rings, earrings, pendants

Zirconium (Zr): Black, dark gray → favored for men’s jewelry, bag clasps, zipper pulls

Chromium (Cr): Bright silver, strong corrosion resistance → bracelet locks, watch parts

Alloys & Precious Metals (Au, Pt): Premium finishes for high-end customization

Compound Targets (TiN, TiCN, ZrN): Hard coatings with unique tones → chains, buckles

 

Why Targets Matter

For both jewelry and hardware, the target determines:

Color → fashion-forward finishes from gold to rainbow

Durability → resistance against scratching and abrasion

Corrosion Resistance → protection against sweat, humidity, and daily exposure

Brand Value → flawless surfaces that elevate craftsmanship and trust
