Hardcoat as a Dynamic Seal Surface

I plan on using hard anodize as a seal surface (mates with a lip seal on a rotary joint to retain low pressure lubricating grease.) Can I expect any wear/leakage issues with the hard anodize

It should work very well, but you may want to consider lapping it to be certain it is smooth.

If the part is not flexed or mechanically abused in that area, it should work. (IE: the anodize is not damaged or cracked) This also assumes that there is not a thermal coefficient of expansion problem with dissimilar metals. Winters are cold in ND and summers can be really hot in the sun.
