How does surface finish affect a part’s function?
How does surface finish affect a part’s function? Surface finish determines how a surface looks, feels, and wears.
Which texture of surfaces wears more quickly?
Rough 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.
