It has a direct impact on the mechanical parts of friction, lubrication, sealing, wear resistance, fatigue resistance, electrical conductivity, corrosion resistance, paint and other functions. Considering the extensive and diverse effects of surface roughness on the function of the part, especially for small surface segments that are not a sampling length or only 2 to 3 contour peaks or valleys, or are sensitive to fatigue damage due to stress concentration Take
