摘要
The surface of T1811 alloy was treated by electrospark surface strengthening (ESS) with Mo electrode in the air and in the silicone oil environment to explore ways to eliminate the strengthening layer cracks and flaws. ESS was combined shot peening in order to synergistically improve the fretting fatigue (FF) resistance of Ti alloy. The results show that the Ti811 alloy treated by ESS in the air induces the Ti alloy surface cracking, which leads to its fretting fatigue resistance decreasing. The Ti811 alloy treated by ESS in the silicone oil not only eliminates the surface micro cracks, but also significantly improves the wear resistance of Ti alloy due to the better lubrication. The fretting fatigue resistance of Ti alloy is also improved synergistically by ESS in the silicone oil combined shot peening post treatment.
