The production of thin hard anodized coatings on Single Point Diamond Turned (SPDT) 6061-T6 aluminum has been studied. The investigation centered on producing a surface finish of less than 10 microinch after anodizing. By starting with a 2 microinch (AA) surface finish and controlling time, temperature, current density and solution chemistry, coatings with surface finishes of 8 microinch and a thickness of .0003 inch, are obtained. Surface roughness from several anodizing solutions is compared. The operational life of a PTFE sliding seal against a coated cylinder bore is used as verification of finish quality.
