Sulfuric Acid Anodizing | MIL-A-8625 Type II - Anoplate
What is Sulfuric Acid Anodize / MIL-A-8625 Type II? The sulfuric acid process is the most common method for anodizing. The sulfuric acid anodize process films range from .0001"-.001" thick. The overall thickness of the coating formed is 67 percent penetration in the substrate and 33 percent growth over the original dimension of the part.

The sulfuric acid anodizing process involves immersing a metal part in a sulfuric acid solution while applying a direct electrical current. Sulfuric acid anodizing is an electrochemical process used to create a protective layer of aluminum oxide on the surface of …
A look at Sulfuric Anodizing: how it works and where it’s used
Feb 28, 2024 · Sulfuric acid anodization, also known as Type II anodizing, is an anodization process that uses sulfuric acid as the primary agent to form a corrosion resistant surface.

Increase p int adhesion: The tightly adhering anodic coating offers a chemically active sur- face for most paint systems. Anodic films pro- duced in sulfuric acid baths are colorless and offer a base for subsequent clear finishing sys- tems.
Sulfuric Acid Anodizing: Process, Materials, Benefits, And …
Sulphuric acid anodising is an electrolytic process using electricity (DC current) and a sulphuric acid electrolytic solution causing oxidation of the aluminium surface to form a thin “harder” film of aluminium oxide under controlled conditions.
Hardcoat Anodizing | Sulfuric Acid Anodize| Chromic Acid Anodize ...
Hardcoat anodize, while usually done in a sulfuric acid based electrolyte, is much thicker and denser than the more conventional sulfuric anodize. Hardcoat is specified for aluminum components subject to extreme wear applications where superior abrasion resistance is needed, or corrosive environments where a thicker, harder, more durable ...
Sulfuric Acid Anodizing | Silvex Surface Technology
Sulfuric acid is the most widely used solution to produce an anodized coating. It is less expensive, more environmentally friendly and easier to dye than chromic acid anodize. The Type II coating as designated by the Mil-A-8625 standard has a moderate thickness 0.00007” to 0.001”.
Some of the specification ranges for sulfuric acid are too high for efficiency – too low for various alloys – and too wide open for quality and energy savings.
Boric-sulfuric acid Anodization (BSAA), a proprietary Boeing product that requires license fees, is NAVAIR’s only fully implemented alternative to CAA where corrosion resistance, paint adhesion, and fatigue resistance are required.
