Critical Factors Governing the Frictional Coefficient in Mg Alloys—Learn From Machine Learning

open access: yesEngineering Reports, Volume 7, Issue 5, May 2025.
Machine learning models were successfully used to predict the friction coefficient of Mg alloys based on composition, processing, mechanical properties, and tribological parameters. Normal load, elastic modulus, and Zn content are the most important factors in governing the friction coefficient in Mg alloys. ABSTRACT Data‐driven methods are emerging as
