| 摘 要： | The different change tendencies of 2-and 3-dimensional surface roughnesses of 40Cr steel aremeasured and analysed.In 2-dimensional parameters,the data are measured amplitude parametersR_a ,R_q ,R_(pn),spacing parameters S_m,S,q and shape parameters Δq,T_p %,R_(sk),R_(ku)..In3-dimensional parameters,the similar amplitude and shape parameters are measured.The au-thors found that ion implantation lcads to reduction of the values of the amplitude parameters ofthe surface roughness remarkably.The values of the spacing parameters have no regular changes.The changes of surface profiles before and after ion implantations have been measured in detail.Inaddition,the auto-correlation function and the power spectrum are analysed for the surfaces ofdifferent implanting parameters.It is concluded that in the observed frequency range,the intensi-ties of various frequencies decrease widely and the coefficients of the auto-correlation of surfacesdecrease after ion implantation.
