ABSTRACT
The friction and wear properties of milled surfaces directly affect the stability and reliability of mechanical equipment, and its friction and wear mechanism are not clear enough because it is affected by many factors. In this paper, the friction and properties of milled surfaces of the metallic material HT300 at the micro-nano scale were investigated. First, milling experiments were carried out on HT300 metallic materials to obtain milled surfaces on the micro-nano scale with machined textures. Then, the friction and wear experiments on the milled surface were carried out under different normal loads and displacement amplitudes. Next, the friction coefficient curves during frictional wear were analyzed, and the effects of normal load and displacement amplitude on the average friction coefficient were investigated. Finally, the wear profiles in the friction and wear process were analyzed and the relationship between normal load, displacement amplitude and maximum wear depth were revealed. In this paper, the friction and wear laws of milling surfaces at micro-nano scales under different loading conditions are investigated, which provides theoretical support for the study of friction and wear on machined surfaces.
