In this study, by integrating the strengthening strategy with solid lubricant modification, we fabricated Cu composite coatings that incorporate both strengthening W particles and lubricative graphene nanoplatelets (GNPs) through cold spraying. Experimental findings demonstrate that the Cu-W-GNPs coating achieves a remarkably low coefficient of friction (COF) of 0.16 and a wear rate of only 1.9 × 10−5 mm3/N·m. This synergy effectively prevents the formation of a brittle nanostructured tribolayer and dynamically recrystallized structures, fostering a more resilient subsurface layer, which results in decreased COF and wear rate. This study not only underscores significant tribological improvements offered by the Cu-W-GNPs composite coating but also provides a sophisticated strategy for developing innovative metal/solid lubricant coatings with enhanced low-friction and wear-resistant properties.
