- Reduced risk of Galling
- Abrasion Resistance
- And more!
Technical Notes for AMS-2488
Purchase order should include as much of the following as possible
- AMS2488E
- Basis metal to be anodized
- Special features, geometry or processing present on parts that require special attention by the anodizing processor
- Periodic testing frequency and sample quantity
- Whether approval is based on approval of process/control factors or sample part
- Quantity of pieces to be plated
- Permissible electrical contact locations
About
This specification establishes the engineering requirements for producing an anodic coating on titanium and titanium alloys and the properties of the coating.
Application
These coatings have been used typically as a lubricating and anti-galling coating for elevated temperature forming, as an isolating film for increased resistance to galvanic corrosion, to provide improved wear resistance and as a pretreatment for the application of solid film lubricants, but usage is not limited to such applications.
AMS-2488 Classification
Coatings are classified by end-product applications, as follows:
- Type 1 - As a coating for elevated-temperature forming.
Anodizing shall produce a dimensional increase of 0.0002 to 0.0004 inch (5 to 10 µm) per surface, determined by measuring the same location on parts or specimens before and after anodizing using a micrometer accurate to 0.0001 inch (2.5 µm), by eddy current measurements in accordance with ASTM B244, or other method acceptable to purchaser. If specimens are used, they shall be fabricated from the same alloy and condition as the parts and shall be processed with the parts represented. - Type 2 - As an anti-galling coating without additional lubrication or as a pretreatment for improving adherence of film lubricants and in application where increased resistance to galvanic corrosion is required.
Shall be such that there is no measurable dimensional change when measured with a micrometer accurate to 0.0001 inch (2.5 µm).
Type 2 shall be furnished unless Type 1 is specified.

Electroplating
Electroplating
Electroplating is a process by which one metal is deposited onto a base metal (substrate). These deposited metals offer a variety of benefits including thermal and electrical conductivity, corrosion resistance and more. AOTCO electroplates a wide variety of both standard and exotic metals.

Anodizing
Anodizing
Sometimes called a “conversion coating” Anodizing is an electrolytic process in which an oxide (anodic) layer is chemically built on the surface of the substrate material, providing anti-corrosion and other benefits. AOTCO offers, Type I, Type 2, Type 3 and Titanium anodizing services.

Passivation
Passivation
Passivation is a term for a variety if processes that make a metal (most commonly stainless steel) or other substance unreactive, or passive, by altering the surface layer or coating the surface with a thin inert layer. AOTCO performs both citric and black oxide passivation techniques to a range of specifications.
