1. Why Gold-Plated Silver Bracelets Tarnish

1.1 The Science Behind Oxidation & 변색

  • Silver Oxidation: When silver (Ag) reacts with sulfur (H₂S) in the air, it forms 황화은 (Ag₂S), leading to black tarnish.

  • Gold Plating Wear-Off: 시간이 지남에 따라, the thin gold layer erodes, exposing the silver underneath to oxidation.

1.2 변색을 가속화하는 요인

✔ Exposure to Moisture & 습기 (땀, 물, humid climates)
✔ Contact with Chemicals (향수, 외용 물약, 염소, 세척제)
✔ Friction & Abrasion (rubbing against skin, 의류, or other jewelry)
✔ Air Pollution & 황 노출 (common in urban areas)

2. 재료 선택: Choosing the Right Base Metal & 도금

2.1 High-Quality Sterling Silver (925 은) as the Base

  • 왜 925 은?

    • 포함 7.5% 구리 내구성을 위해.

    • Less prone to rapid tarnishing compared to pure silver.

  • 니켈 프리 & 저자 극성 옵션 – Reduces skin irritation.

2.2 Optimal Gold Plating Thickness

  • 표준 금 도금 (0.5-1 미크론) – Wears off quickly.

  • Heavy Gold Plating (2-3 미크론) – Lasts longer before exposing silver.

  • 18K vs. 24K 금도금 – 18K is more durable due to alloy hardness.

2.3 Alternative Base Metals for Extra Protection

  • Brass or Copper Underlay – Cheaper but requires thicker plating.

  • Rhodium Undercoating – Adds a protective barrier between silver and gold.

3. Advanced Plating Techniques to Prevent Oxidation

3.1 Multi-Layer Plating Process

  1. Nickel or Rhodium Undercoat – Prevents silver from reacting.

  2. 두꺼운 금도금 (2-3 미크론) – Slows down wear.

  3. Protective Top Coat (선택 과목) – Clear lacquer or anti-tarnish sealant.

3.2 PVD (물리적 증기 증착) 코팅

  • More Durable Than Electroplating – Resists scratches & fading.

  • Used in Luxury Jewelry – Longer-lasting shine.

3.3 Pulse Plating vs. Traditional Plating

  • Pulse Plating – Creates a denser, more even gold layer.

  • Traditional DC Plating – Cheaper but less uniform.

4. 보호 코팅 & Sealants

4.1 Clear Lacquer Coating

  • 프로:

    • Creates a waterproof barrier.

    • Inexpensive & easy to apply.

  • 단점:

    • Can wear off over time.

    • May cause allergies if low-quality.

4.2 Anti-Tarnish Solutions

  • Jewelry Shield Sprays – Temporary protection.

  • Silicon-Based Sealants – Longer-lasting than lacquer.

4.3 Wax or Oil Coating (For Storage)

  • Beeswax or Jewelry Wax – Protects during shipping/storage.

5. Proper Storage & Handling During Production

5.1 Preventing Tarnish Before Sale

  • Anti-Tarnish Paper or Strips – Absorbs sulfur in packaging.

  • Airtight Polybags – Reduces air exposure.

5.2 Humidity-Controlled Storage

  • 실리카겔 팩 – Keeps moisture away.

  • Dehumidifiers in Storage Rooms – Ideal for tropical climates.

6. Post-Production Care & 유지 보수 팁

6.1 Cleaning Gold-Plated Silver Bracelets

  • Do’s:

    • 사용 a soft microfiber cloth.

    • 다음으로 청소하세요 온화한 비누 + lukewarm water.

  • Don’ts:

    • 피하다 베이킹 소다, toothpaste, or harsh chemicals.

    • 절대 scrub aggressively.

6.2 입다 & Care Instructions for Customers

✔ 수영/샤워 전에 제거하십시오.
✔ Avoid contact with perfume & 로션.
✔ 건조한 상태로 보관하십시오, airtight jewelry box.

7. 품질 관리 & 테스트 방법

7.1 염수분무시험 (ASTM B117)

  • Simulates long-term exposure to humidity.

  • Checks plating durability.

7.2 문지름 테스트 (ISO 3160-2)

  • Measures resistance to friction.

7.3 XRF Testing for Plating Thickness

  • Ensures gold layer meets specifications.

8. 지속 가능한 & Long-Lasting Solutions

8.1 Recycled Silver & Eco-Friendly Plating

  • Cyanide-Free Gold Plating – Safer for workers & environment.

8.2 Educating Customers on Longevity

  • Include care cards with purchases.

  • Offer replating services.
