Hard Anodizing

We are looking into coating an aluminum extrusion with a hard anodized coating to use as the track base for a linear slide. The linear slide rolls with 52100 steel guide wheels that will ride directly on the coated aluminum surface. Loads will be relatively light. Is there a coating or a process that will work with a minimal amount of wear? or are the steel guide wheels too much for any coating? The slides may be lubricated.

Thanks

We have a chromium nitride coating that we've been able to deposit on aluminum alloys without mechanical degradation. The hardness of the coating is around 2100 Hk, and the adhesion is outstanding. We'd be happy to look at coating the rails for you.
