摘要：
In the hot extrusion of aluminium alloys, friction at the workpiece/tools interface has great influence on the die wear, profile surface quality and extrusion load. The friction coefficient is also an important thermal boundary condition in the FE simulation of aluminium extrusion, which is affected by many factors and hard to be quantified. To obtain accurate simulation results, reasonable friction models and friction coefficient should be adopted. The tribological behaviors of contact interfaces in the hot extrusion of aluminum alloy were revealed. The effect of friction and wear on the surface quality of the profile in the bearing was analyzed. The research status and development of surface treatment techniques were comprehensively reviewed and evaluated. The friction models and equivalent characterizations being used for the FE simulation of aluminium extrusion at different contact interfaces were summarized. The main problems of friction in the hot extrusion of aluminium alloys were put forward. © 2017, Science Press. All right reserved.
