not suction...adhesion

Get two surfaces sufficiently close and they will adhere. Or put another deformable material in between (adhesive) and they will adhere. Forces holding together are molecular attractions of the two surfaces. This force will be a force holding the surfaces together. It will be proportional to area so corrugated will be less than flat.

Resistance sliding force is not related.

Related event. The mars rover sampling tubes were cleaned to the extreme. There were so clean there was no foreign material, or oxide, on them. And they were perfectly flat. When assembled they welded together. They had to add a layer of contamination that would not be confused with mars stuff to keep them from welding.
