Surface Roughness 3D Parameters Calculations

By Jānis Rudzītis, Māris Kumermanis and Anita Avišāne


At present surface roughness profile parameters are determined by standards. At the same time different exploitational properties of details are determined with the help of 3 dimensional image - microtopography (Fig. 1). In microtopography surface roughness including nanocoatings is expressed by random field h (x, y) of two variables x, y - cartesian coordinates of surface point

Topics: Surface nanocoatings, 3D parameters, mean value, dispersion
