The influence on the tribological performance of cylinderliner by microtexturing and micro/nano particles filling was studied,and the influence on friction coefficient and antiwear time of the friction pairs by microtexturing and micro/nano particles filling was explored under the oilrich and boundary conditions.The results show that under the oilrich condition,the cylinderliner sample with both end surface microtexturing and filled by serpentine and supramoly micro/nano particles has the minimum friction coefficient,its friction coefficient is 1399% lower than that of mechanical honing sample.Under the boundary condition,the cylinderliner sample with all surface microtexturing and filled by serpentine and supramoly micro/nano particles has the maximum antiwear time,its antiwear time is 8579% more than mechanical honing sample.During tests,the overflow rate of micro/nano particles in surface crater is gradually declined with the increasing of test time,and finally approaches to 0.
