NOVELTY - Nanometric coating composition comprises 20-30 pts. wt. iron, 40-50 pts. wt. germanium, 5-10 pts. wt. tungsten, 26-39 pts. wt. titanium, 6-9 pts. wt. cannabinol, 4.75 pts. wt. microelements comprising molybdenum, boron and silicon mixed with graphene oxide in mass ratio of 1:0.75:0.5:1. USE - Nanometric coating composition. ADVANTAGE - The nanometric coating composition ensures good corrosion and wearing resistance, and has improved microstructure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing nanometric coating composition, which involves: (A) preparing preparing nanospheres of iron-graphite-tungten-titanium composite by dry pulverization method; (B) mixing surfactant and microelements with obtained product to obtain prepare nanometric powder; and (C) preparing coating composition on chromium mold (4Cr13) having steel basal body surface by supersonic flame spraying method.
