Hard anodize/taber testing

September 17, 2008

Any advice on appropriate conditions to get Hard Anodize 7000 series panels to pass taber testing? Thanks

Hardness (abrasion resistnce) is favored by lower temp, lower concentration, higher current density, and the glycolic/glycerin additive. AND ramp up to the desired current density over a period of 15 minutes before setting the current to remain constant while the voltage climbs.

Also, understand, that becasue of the inverse connical shape of the pore, the pore is smaller (and more abrasion resistant) at the lowest thicknesss.
