Research on Friction and Wear Behavior of W-20%Cu Composite during Super-speed Dry Sliding AITranslate
Abstract AITranslate
Super-speed friction and wear experiments were carried out with a reconstructive Hopkinson bar as the device and the effects were studied of different projectile impact velocity on friction and wear properties of W-20%Cu/7075 Al and W-20%Cu/45 steel.And the wear mechanism was also discussed.The results show that adhesive wear,abrasive wear and oxidative wear happen between W-20%Cu and 7075 Al under the super-speed condition,while adhesive wear and abrasive wear happen between W-20%Cu and 45 steel.W-20%Cu/7075 Al and W-20%Cu/45 steel have the similar friction coefficient of 0.03~0.20,decreasing with the faster sliding speed.With friction frequency increasing at the same sliding speed,the friction coefficient decreases at first,then increases and keep stable at last for W-20%Cu/7075 Al but increases at first,then decreases to keep stable for W-20%Cu/45 steel.Both W-20%Cu/7075 Al and W-20%Cu/45 steel show negative wear rate,and the absolute value of their wear rate has a decreasing trend with sliding speed increasing.
