Oral Presentation Block 1
The effect of graphene on the material properties, friction, and wear of self-lubricating aluminum-based metal matrix composites (MMC) was compared with the effect of graphite as the reinforcement. Notable enhancement of mechanical properties and friction and wear performance was observed with graphene addition. Statistical analysis suggested that a much lesser amount of graphene reinforcement can produce a friction and wear performance similar to that of aluminum MMCs with a higher amount of graphite. Five machine learning (ML) regression models were developed to predict the wear rate and coefficient of friction (COF) of aluminum-graphene MMCs. ML study suggested that the weight percent of graphene, loading condition, and hardness had the largest influence on the wear and friction of aluminum-graphene composites.
