Characterization of AlSi10Mg Alloy Produced by DMLS Process for Automotive Engine Application 2019-28-0134

Considerable weight of an automobile is constituted by the engine and there is scope for improvement in fuel efficiency and emission control through optimization of weight in the engine. In this work, AlSi10Mg alloy produced by the DMLS is suggested for engine application which is a lightweight aluminum alloy. The mechanical properties like tensile strength, compressive strength, and hardness of both cast and additive manufactured alloy are compared followed by analysis of SEM images of tensile test fractured surfaces. The reciprocating wear test is carried out with lubrication (SAE 40 oil) for one lakh cycles at 125°C temperature and Co-efficient of friction (COF), wear rate of the cast and additive manufactured samples were compared. Wear patterns are analyzed using SEM images of the wear tracks.
