This book uses the Al-Si as a base matrix composite, adding the hybrid nanoparticles of MoS2 & BN. It aims to fabricate self-lubrication parts, and the manufacturing process utilizes the technology of powder metallurgy is a favored strategy for manufacturing metal matrix nanocomposites (MMNCs). Aluminum alloys are one of the widely applied composites in MMNCs as base alloys from analysis and manufacturing estimation. As an abrasive material, Boron Nitride (BN) has a long service life and sensible wear resistance. The Molybdenum disulfide (MoS2) could be a 2-dimensional semiconductor matter; it has anti-wear properties, reinforces cohesion, and reduces abrasion. Thus, it has a greasing realization that might utilize as a solid lubricator within severe heat and compression conditions. The thermal stability of BN is far more than that of diamond and has more excellent chemical stability than iron components. Therefore, BN is suitable to use for the protection of components, anti-wear, and anti-corrosion.
