Entity Definition

What is an Anodizing / Surface Treatment Line?

An in-house anodizing and surface treatment line is a chemical processing system comprising multiple tanks for cleaning, etching, anodizing, rinsing, sealing, and drying titanium components. Type II anodizing produces the characteristic color finish on titanium (via light interference), while Type III (hard anodizing) provides enhanced wear resistance and anti-galling properties. In-house surface treatment capability eliminates 1-3 weeks of outsource lead time and gives full control over quality, color consistency, and process documentation per aerospace and medical specifications.

Operations & Capabilities

Surface Treatment Processes

Anodizing and surface treatment lines perform the following critical processes on titanium components:

Type II Anodizing — Standard anodic treatment for color identification (per AMS 2488); produces interference colors (gold, blue, purple, green) based on voltage
Type III Anodizing — Hard anodic coating for wear resistance and anti-galling properties on threaded titanium components
Chemical passivation — Nitric acid or citric acid passivation to remove surface contaminants and restore passive oxide layer (per ASTM B600 / ASTM A967)
Acid pickling / descaling — HF/HNO₃ solution for oxide scale removal after heat treatment or welding
Alkaline cleaning — Degreasing and surface preparation before anodizing
PVD coating (optional) — Physical vapor deposition for enhanced wear resistance, decorative finishes, or reduced friction
DI water rinsing — Multi-stage cascade rinsing for chemical removal between process steps
Typical Products & Components

Typical Processed Components

Anodizing and surface treatment lines are used to process the following titanium components:

Aerospace fasteners — color-coded by grade or specification via Type II anodizing
Medical implants — passivated and Type II anodized for biocompatibility and identification
Surgical instruments — passivation for corrosion resistance and cleanliness
Automotive performance components — Type III anodized for wear resistance on threaded fasteners
Marine hardware — anodized for corrosion protection and color coding
Architectural components — decorative Type II anodizing for aesthetic finish
Oil & gas downhole tools — Type III anodized threads and sealing surfaces for anti-galling
Primary Industries

Primary Industries

Anodizing and surface treatment lines serve as critical finishing equipment across these industries:

Aerospace — Fastener color coding, anti-gall anodizing for threaded components
Medical — Implant passivation and identification anodizing per ASTM F86
Automotive — Performance component finishing and wear protection
Marine — Corrosion protection and identification color coding
Oil & gas — Anti-galling surface treatment for downhole tool connections
Architecture — Decorative titanium finishing for building components
Alternative & Complementary Options

Alternative Surface Treatment Solutions

Depending on volume and certification requirements, the following alternatives may be considered:

Outsource Anodizing — Eliminates CAPEX and environmental compliance burden; introduces 1-3 week lead time and external quality risk
Small Manual Line (200 L tanks) — Lower capacity for prototype and low-volume processing; not suitable for production volumes
PVD Coating Only — Alternative wear-resistant coating without anodizing chemistry; higher cost per part
Chemical Passivation Only — Minimum surface treatment without anodizing; acceptable for non-critical applications per ASTM B600
