1) "running-in" stage: the surface layer of PTFE mixture to the other side of the surface of the dual-filled surface to fill the pit, and the formation of transfer film, at this time, the friction coefficient of material wear faster. As shown in the curve Ⅰ. 2) "stable" wear stage: the friction after running into a friction between the PTFE, the friction coefficient is low and stable, low wear rate of the material and stable. As shown in the figure Ⅱ area curve. 3) "abrupt" wear stage: PTFE lubricant in the pores of the porous layer is consumed, and a sufficient amount of lubricant can not be obtained between the friction surfaces. Friction between the poor lubrication, friction coefficient increased rapidly, the rate of wear and tear of the material also sharply accelerated until 70% of bronze exposed, SF-1 life is close to termination. As shown in the figure III curve.
