WebRough surfaces generally wear more rapidly and have greater friction coefficients than smooth surfaces. Typically, roughness is a dependable predictor of mechanical part performance, as irregularities tend to form nucleation sites for breaks or corrosion. Conversely, roughness may encourage desired adhesion. Defining Surface Roughness WebRoughness affects various part characteristics, including the amount of wear, the ability to form a seal when the part makes contact with something, and the ability to coat the part.
