The Effect of Nano-Graphite Particle to the Friction and Wear Performance of Al-Mg Matrix Composite Material
Abstract:
In this paper, with the combination of powder metallurgy and hot pressing method, the nano-graphite Al-Mg composite material was made. This method succeeds in solving the difficulty that graphite particle directly melted with Al-Mg melt, which investigates the amount of nano-graphite’s impact on the abrasion resistance of Al-Mg composite material. The result shows that nano-graphite particle easily to scattered in the matrix when the nano-graphite particle amounts to 1﹪ which can decrease the friction coefficient of composite material. But the material of wear extent increases accordingly along with the increase of the content of nano-graphite.
