Laser sintering is one of the most widely used methods for fabricating advanced materials such as metal matrix composites (MMC). It offers a great deal of flexibilities to deal with complex shapes. Laser sintering is also a critical method to deal with constituents of metal matrix composites with higher melting point and hardness. In the present work, an attempt is made to present an experimental study wherein Al-MMC is fabricated first with the powder metallurgy route. Then surfaces of MMC are treated with laser. The effect of laser treatment on hardness and wear property is investigated. The treatment of laser on the surface of MMC resulted in increased hardness as compared to untreated MMC, and the wear resistance is found better along with the increased percentage of reinforcement particles. The work also presents a study on the application of laser to process Metal Metric Composite. It gives an idea of different associated process parameters like laser power, scanning speed, and their effect on MMC.
