Abstract
Steels with and without bionic non-smooth surfaces were prepared and then their friction and wear properties under dry/lubricant wear conditions were evaluated. The average friction coefficients of the specimens with non-smooth surfaces were relatively low under dry wear condition. Moreover, the specimens with or without bionic non-smooth surfaces had lower friction coefficients under the load of 200 N compared with the load of 300 N. The worn morphologies of the specimens after the friction tests were observed using the scanning electron microscope for analysing the worn characteristics. The energy-dispersive spectrometer) was implemented to analyse the wear mechanism. The results showed that the bionic surfaces of testing samples had better wear resistance and provided stable friction coefficient to some extent.
