What is Electropolishing of all vacuum-facing surfaces?

Electropolishing of all vacuum-facing surfaces capability for titanium components

Surface engineering capability for Electropolishing of all vacuum-facing surfaces, 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 for Semiconductor present unique challenges: Balancing dimensional accuracy with cost per part. Process selection (mill vs. turn vs. EDM vs. laser) 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)
