Purpose: This specification establishes the engineering requirements for producing an electrolytic conversion (anodize) coating on titanium and titanium alloys and the properties of the coating. Application: Type 1 is used primarily as a lubricating and antigalling coating for elevated-temperature forming of titanium and titanium alloys. Type 2 is used primarily for protection against galling and galvanic corrosion@ for improved wear resistance@ and for pretreatment in the application of dry film lubrication. Classification: Coatings are classified by end-product application@ as follows: Type 1 - As a coating for elevated-temperature forming. Type 2 - As an anti-galling coating without additional lubrication or as a pretreatment for dry film lubricants. Such coatings also are compatible with hypergolic propellants such as hydrazine-unsymmetrical-dimethlhydrazine and nitrogen tetroxide@ and are electrically semiconductive. Type 2 shall be furnished unless type 1 is specified.
