▎ 摘　　要

NOVELTY - The nanocomposite coating (12) includes graphene particles (14) and molybdenum disulfide particles (16), which have particle size of less than ten nanometers. The graphene particles are in an amorphous phase (18). The molybdenum disulfide particles are in monocrystalline phase (20). The weight of graphene particle is 60-95% by weight of the nanocomposite coating, and the weight of molybdenum disulfide particle is 5-40% by weight of the nanocomposite coating. USE - Nanocomposite coating used for coating tip of cutting tool. ADVANTAGE - The particle size of the graphene particles and molybdenum disulfide particles being less than ten nanometers results in minimal dislocation movement of the particles, thus increasing the hardness of the coating. The nanocomposite coating enhances the hardness of the cutting tool tip. The coating includes silicon dioxide particles that has a thermal expansion coefficient which provides stability during high temperatures by preventing from forming cracks in cutting tool tip, thus reducing embrittlement of the nano-composite coating. The coating includes titanium dioxide particle that retains sharp cutting edge at high temperature, thus providing firmness and strength to the cutting tool tip during machining. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a process for coating the tip of cutting tool using the nanocomposite coating. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the cutting tool which includes a nanocomposite coating.
