NOVELTY - Graphene coating material comprises 50-60 pts. wt. nickel, 1-5 pts. wt. graphene material, 5-10 pts. wt. alumina, 20-40 pts. wt. titanium, 1-3 pts. wt. molybdenum, 10-15 pts. wt. chromium, 40-60 pts. wt. silicon, 7-13 pts. wt. silicon dioxide and 0.8-1.5 pts. wt. cobalt. USE - Graphene coating material for enhancing surface hardness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for enhancing the surface hardness of the mould, which involves: (A) weighing 50-60 pts. wt. nickel, 1-5 pts. wt. graphene material, 5-10 pts. wt. alumina, 20-40 pts. wt. titanium, 1-3 pts. wt. molybdenum, 10-15 pts. wt. chromium, 40-60 pts. wt. silicon, 7-13 pts. wt. silicon dioxide and 0.8-1.5 pts. wt. cobalt; (B) ispersing and uniformly mixing toobtain mixed raw material; and (C) depositing plating film on the surface of the mould.
