Aluminum Pulley mounted on a steel? flange.

I am wondering if there is any dissimilar metal contact issues we need to be aware of and whether the two metals need to be separated by a barrier of some kind....plastic, paint etc.

Aluminum strength suffers quickly when this is an issue and with the rubber belt whirring around I imagine there might be some significant electrical potential being developed.

Any reports of issues with this?
The factory pulley is anodized aluminum as well.
