) are concerned. A large number of micro topography samples are randomly generated first using the rough surface simulation method with FFT. Then roughness parameters of the simulated roughness profiles... parameter are discussed. The constructed computing formulae provide an approach to active modeling of rough surfaces with given roughness parameters. Key words: micro topography; rough surface......
out at irradiation angles of 45? and 10?, respectively. The surface roughness and topography were measured to estimate the quality of surface finish. The results show that the ion irradiation is very effective to reduce the surface roughness, which can be improved more significantly at irradiation angle of 10? than at 45?. The technology of surface finish with ion beam irradiation is suitable......
