Title:
 Anodic Treatment - Titanium and Titanium Alloys
Solution pH 13 or Higher
Number:
 AMS 2488
Revision:
 D
Scope:
 This specification establishes the engineering requirements for producing and anodic coating on titanium and titanium alloys and the properties of the coating. These coatings have been used typically as 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 application of solid film lubricants, but usage in not limited to such applications.
   
Classification:
  
Types
Coatings are classified by end-product application, as follows:
   
Details Description Can Do
Type 1 As a coating for elevated-temperature forming. Yes
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. Such coatings also are compatible with hypergolic propellants such as hydrazine-unsymmetrical-dimethylhydrzine and nitrogen tetroxide, and are electrically semiconductive. Yes
