摘要：
The friction and wear behaviors of copper-based graphite seal material used in liquid rocket engine were investigated by means of pin-on-disk machine. The effects of load, velocity and temperature rise on friction and wear behaviors of the copper-graphite material were analyzed. Results show that: 1) It is not easy to form copper-graphite transfer film under water lubrication condition, so the friction coefficient under water lubrication condition is higher than that under dry friction; 2) Under the condition of water lubrication, the wear mechanism is adhesive wear and abrasive wear, and properly increasing load and decreasing velocity can reduce the wear rate of the copper-based graphite material; and 3) Under the condition of dry friction, the wear mechanism is adhesive wear, and properly decreasing load and increasing speed can help reduce the wear rate of copper-based graphite material. © 2017, Editorial Office of Journal of Xi'an Jiaotong University.
