The finish of a surface can really affect how much it wears down when things stick to it.
When a surface is smoother, it creates less area for contact, which can lower wear by a lot—sometimes by 30% to 50%!
For example, if the surface roughness (Ra) is less than 0.2 µm, it can cut down adhesive wear by as much as 65%.
On the other hand, if a surface is rougher, it can lead to more problems with sticking. This can make materials wear out faster, by about 20% to 40%.
So, keeping surfaces smooth can help them last longer!
