Dual-motion fretting tests of flat cortical bone specimens from fresh human mandible against pure titanium (TA2) ball were carried out on a modified test rig with tilt angle of 45°. The imposed maximal loads varied from 100 to 200N. Dynamic characteristics of dual-motion fretting tests were analyzed in combination with micro-examinations via optical microscopy (OM), laser confocal scanning microscopy...
Under the lubrication by the imitated human physiological solution, the fretting behaviors of flat cortical bone were investigated against titanium (TA2) and its alloy (TC4) ball counterpart. The friction logs and coefficients were recorded automatically. The worn surfaces of cortical bone were analyzed by means of laser confocal scanning microscopy. The results show that friction logs transform from...
