This specification establishes the requirements for a hard aluminum oxide coating, impregnated or codeposited with polytetrafluoroethylene (PTFE) on aluminum alloys.


This process has been used typically to increase, by the formation of a dense, PTFE-impregnated aluminum oxide or codeposited PTFE-aluminum oxide layer, surface hardness and resistance to abrasion and corrosion of aluminum alloy parts containing, in general, less than 5% copper or 8% silicon or a total of 8% of both. See 8.6.


The processes covered by this specification are classified as follows:

Type 1 - PTFE-impregnated aluminum oxide

Type 2 - Codeposited PTFE and aluminum oxide

If a specific type is not specified, Type 1 shall be supplied.
