Al and Mg nanocomposites have good mechanical properties and are potential tribological candidates for applications where weight-reduction is a critical factor, such as in automotive, aerospace and sports. This chapter presents the tribological characteristics of various Al and Mg nanocomposites. The tribological properties of wear and friction of the light-metals nanocomposites are influenced by several factors such as: process and process parameters, composition and microstructure, mechanical properties, heat treatment to enhance mechanical properties, applied external parameters of velocity and load, and formation of in situ protective films/layers. Examples of tribological investigations of nanocomposites that highlight these influencing factors are presented in the view of providing a comprehensive outlook on the tribology of light-metals nanocomposites. Some suggestions for future work are also mentioned.
