AMS 2482
Specifications

Technical Notes

Purchase Order shall specify not less than the following

  • AMS2482E
  • Basis metal to be anodized
  • Special features, geometry or processing present on parts that requires special attention by the processor
  • Quantity of pieces to be anodized

Classification

The processes covered by this specification are classified as follows:

  • Type 1 – PTFE-impregnated aluminum oxide
  • Type 2 – Codeposited PTFE and aluminum oxide

Thickness

AMS2482 designates finished coating thickness of 0.002 inch ± 0.0005 (51 µm ± 13). Other coating thicknesses may be specified designating the nominal thickness in thousandths of an inch (25 µm). A tolerance of ±0.0005 inch (±13 µm) in thickness of coating will be allowed. AMS2482-3 designates a finished coating thickness of 0.003 inch ± 0.0005 (76 µm ± 13).

Coating thickness requirements shall not apply to blind holes or recesses with depth greater than twice the diameter or in open holes with depth greater than seven times the diameter unless a specific coating thickness is specified in those areas.

Considerations

  • The anodize process can reveal the presence of metallurgical damage which had occurred prior to the submittal of parts to the anodize processor. Examples are:
    • Damage from improper welding
    • Weld repair of castings after final heat treatment
    • Incorrect initial heat treatment
    • Raw material chemical segregation
    • Other prior metallurgical conditions which may be detrimental to the final use of the component.
  • The purchaser or cognizant engineering organization may elect to place such components on material review pending further testing or analysis.

The anodizing processor shall not be responsible for the presence of these types of metallurgical anomalies occurring prior to submittal of parts for anodizing.

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.
