Effect of oxide formed on friction behavior of aluminium alloy during fretting were studied. The ambient pressure was varied from 10^<-3> to 10^5 Pa. The experiments were carried out at a normal load of 1 N, a slip amplitude of 100μm, a frequency of 3 Hz and 10^4 cycles. It was found that coefficient of friction became minimum at 10^<-1> Pa. In order to examine the formation and removal of oxide debris particles on the wear scar, another experiments were carried out in which the ambient pressure was changed alternately from 10^5 to 10^<-3> Pa for every 2×10^3 cycles. Coefficient of friction is lower at 10^<-3> Pa than at 10^5 Pa. That is because oxide remained on the surface prevents the strong adhesion at 10^<-3> Pa and oxide particles behaves as abrasive at 10^5 Pa.
