What is Surface treatment?

Surface treatment capability for titanium components

Surface engineering capability for Surface treatment, with process control, bath chemistry monitoring, and batch consistency validation.

Engineering Parameters & Capabilities

Titanium anodizing (AMS 2488) grows a controlled oxide layer through electrochemical conversion in an electrolyte bath. Type II produces interference colors (gold, blue, purple, green) for identification and cosmetics. Type III (hard anodizing) produces a thicker, abrasion-resistant oxide, specifically for titanium components. Precision titanium components present unique challenges: balancing dimensional accuracy with cost per part. Process selection (mill vs. turn vs. EDM vs. laser) is optimized for each feature.

Parameter Specification
Coating Electrochemical oxide conversion; not a deposit
Thickness Type II: 0.5–5 µm / Type III: 5–25 µm
Colors Gold (15V), blue (40V), green (70V), purple (90V)

Engineering Capabilities & Limits

Surface engineering capability for Surface treatment, with process control, bath chemistry monitoring, and batch consistency validation.

Hole Types Supported

N/A

Heat Control Measures

Electrolyte bath at 20–24°C (Type II) or –5–0°C (Type III). Voltage ramp is programmed to prevent localized overheating and burning.

Flatness & Stress Relief

No dimensional change—surface conversion only. Pre-treatment finish is preserved through the process.

Tolerance

Coating: 0.5–5 µm (Type II) / 5–25 µm (Type III); no dimensional change

Frequently Asked Questions

What titanium grades are suitable for Surface treatment?
Surface treatment can be performed on Grade 1, Grade 2, Grade 5 (Ti-6Al-4V), Grade 7, and other grades. The specific grade selection depends on the required mechanical properties, corrosion resistance, and end-use application requirements.
What tolerances can be achieved with Surface treatment?
Typical achievable tolerances for Surface treatment are Coating: 0.5–5 µm (Type II) / 5–25 µm (Type III); no dimensional change. Tighter tolerances may be possible depending on part geometry, material condition, and quantity. Our engineering team reviews each project to determine the optimal tolerance-cost balance.
What quality certifications apply to Surface treatment?
All Surface treatment operations are performed under ISO 9001:2015 — Quality Management System, AS9100D — Aerospace Quality Management, ASTM B265 — Titanium Strip, Sheet, and Plate Standard certified quality management systems. Full traceability documentation, material certifications (EN 10204 3.1), and inspection reports are provided with each shipment.
What is the typical lead time for Surface treatment projects?
Lead times for Surface treatment vary by complexity and quantity. Prototype quantities (1-10 units) can typically be completed in 3-7 business days. Production quantities require 15-25 business days. Rush orders are available for qualifying projects. Contact our sales team for a specific timeline.
Can you provide DFM feedback for my Surface treatment design?
Yes. We provide free Design for Manufacturability (DFM) analysis for all new projects. Simply upload your CAD file (STEP, DXF, or DWG format) and our engineering team will review your design and provide optimization suggestions within 24 hours.
