Friction and Wear Performance of Nano-graphite/Al Matrix Composite Material

Powder metallurgy was used in preparing the nano-graphite/Al matrix composite material.Microstructure indicate that the dispersibility is more homogeneous when the proportion of nano-graphite is 1%.The friction result indicate that nano-graphite could decrease the friction coefficient obviously.But when the quantity of the nano-graphite increase,the wear-loss changing of the material increase.
