Ga-based liquid metal may be a novel coolant and lubricant for the steels at high temperature and extreme pressure in the nuclear reactor. It is recently reported that the formation of FeGa3 film may be responsible for the good lubricity of liquid metal, but no proof can clarify this point and its wear behavior is unclear. Therefore, an in-situ FeGa3 film was prepared through the hot-reaction between...
The dry sliding wear behaviors of Mg based nanocomposites were investigated using the ball-on-disk wear tester. The friction coefficient of Mg nanocomposite reinforced with 15 vol% SiC nanoparticles is much higher than pure Mg and AZ31B alloy. Its wear resistance is about 23 times higher than that of pure Mg. Analysis on the surface and debris suggests that the delamination mechanism of Mg has been...
