Surface properties of surface modified steel samples

For a wide range of commercial available surface modifications on stainless steel substrate with two different finishing (2R and 2B) the surface roughness was measured and represented by different surface texture parameters. Beside the usual surface texture parameters like roughness average Ra, root mean square roughness Rq, mean roughness depth Rz and maximum roughness depth Rmax, also values of the height of the highest profile peak Rp and the depth of the deepest profile valley Rv were measured. In addition to the pure roughness parameters some surface texture parameters that represent the material ratios of the roughness core profile depth Rk, the reduced peak height Rpk, the reduced valley depth Rvk and the smallest and highest material ratios Mr1 and Mr2 were tabulated.
