This study explores the tribological performance of microwave-assisted synthesized g-C₃N₄/MoS₂ coatings. The two-dimensional transition metal dichalcogenide (TMD) nanosheet is getting prominence in the study of tribology due to its layered structure. The graphitic carbon nitride (g-C₃N₄) nanosheet was made using the calcination method and its nanocomposite with molybdenum disulfide (MoS₂) was produced using a microwave-assisted method. The structure and morphology of the samples were characterized by some well-known methods, and tribological properties were studied by a pin-on-disc (POD) apparatus. Morphological analysis revealed that graphitic carbon nitride and molybdenum disulfide coexisted, and the layer structured MoS₂ was well dispersed on graphitic carbon nitride nanosheets. BET analysis was used to determine the pore volume and specific surface area of the synthesized materials. The inclusion of MoS₂ nanoparticles caused the composite’s pore volume and specific surface area to decrease. The reduction in g-C₃N₄ pore volume and specific surface area confirmed that the pores of calcinated graphitic carbon nitride were filled with MoS₂ nanoparticles. The tribological property of g-C₃N₄/MoS₂ nanocomposite was systematically investigated under different factors such as applied loads (5N to 15N), sliding speed (500 to 1000 mm/s) and material composition (uncoated, MoS₂-coated, 9 wt.% of g-C₃N₄ and 20 wt.% of g-C₃N₄ in the composite). The optimal composite material ratio was taken 9%, by weight of g-C₃N₄ in the g-C₃N₄/MoS₂ composite for a variety of levels of loads and sliding speeds. The results indicates that the incorporation of g-C₃N₄ in nanocomposites could reduce friction and improve wear life, which were better than the results with single MoS₂. This study demonstrates a solution to broaden the possible uses of g-C₃N₄ and MoS₂-based materials in the field of tribology.
