Effect of MoSi2 addition on the tribological performance of Cu–GNS composites under thermal and current-carrying conditions

Key Points

• Tribological performance improved significantly with MoSi2 addition in Cu-GNS composites under thermal conditions.
• Under tested conditions, the composites showed enhanced wear resistance and friction reduction, indicating a potential for greater efficiency.
• Analysis of wear behavior and friction under both thermal and current-carrying conditions highlighted the composites' effectiveness.
• These findings support the need for further exploration of MoSi2 addition for enhancing composite materials in engineering applications.
