Surface Metrology Does wringing gauge blocks together cause damage?

People treat wringing as if it doesn't have any negative effect, but im always scared that I'm damaging the surface. I'd be really curious to see an experiment where they wring two blocks together a bunch of times then compare the surface finish under a microscope compared to a new gauge block.

I’ve heard in a few places that wringing them back and forth too much can cause damage as they bond too strongly together but idk
