Not a good thing, but didn't seem to effect the joint.
The rings are ugly enough anyway.
That's the galvanic reaction of the small-surface-area steel ring being electrically overcome by the much greater surface area of the aluminum lug.
Keeping the frame clean and dry is the only way to prevent it, since even galvanizing the steel ring would not prevent it's
surface from oxidizing (what galvanizing is supposed to do, act like a "sacrificial anode").
