As roughness goes hand-in-hand with an enlarged surface area, it affects the wettability of a solid, the contact angle (CA) of a liquid, and the adhesion. Whether the roughness increases or decreases wettability depends on the degree of wettability of the smooth material.

Surface Roughness Chart & Useful Information Predicting the life-cycle of any component is only possible after considering the surface roughness. A surface may seem flawless and perfect to the human eye but when reviewed at a microscopic level it is practically Profilometers are used to measure

Surface roughness is defined as the shorter frequency of real surfaces relative to the troughs. If you look at machined parts, you will notice that their surfaces embody a complex shape made of a series of peaks and troughs of varying heights, depths, and spacing.
