What is MIL-a-8625?
Military specification MIL-A-8625 is the model spec for many components that need anodized for the military and/or aerospace industry. The specification covers all the requirements needed for six types and two classes of electrolytically formed anodic coatings on aluminum and aluminum alloys.
What is MIL-a-8625 type iii?
TYPE III : HARD ANODIC COATINGS MIL-A-8625 Type III sulfuric acid anodizing at 36’F with a coating thickness of 2 – 2.5 mils (very thick!!). This kind of anodizing is accomplished with a bath similar to the standard sulfuric process, but with the temperature reduced to about 0° C to slow the dissolution rate.
Is mil-a-8625 superseded?
Published Date: August 28, 2019. Status: Superseded By: Superseded By: MIL-PRF-8625.
How do you specify anodizing?
The various types of anodized finishes are designated by the letter “A” followed by a two- digit number to call out the specific anodic finish. Finishes designations may be used singly or in conjunction with other designations to specify a complete finishing system.
What is anodic coating?
An anodic coating is a type of coating material that utilizes anodizing to provide increased thickness, color and protection to aluminum or any type of substrate. This coating consists of the oxide film that is created on metal through electrolysis, with the metal acting as an anode.
What is the Defense Standardization Program?
The DSP aims to improve military operational readiness by achieving interoperability with U.S. allies and among the Military Departments; improving logistics support, modernizing existing systems and equipment; and ensuring relevance of standards to the warfighter.
When does MIL-A-8625 revision F become effective?
