Claims preview

1 . A coating material applied to a roller in secondary battery electrode manufacturing equipment, comprising: a buffer layer sequentially including a Cr layer, a CrN layer, a CrN 2 layer, and a CrCH layer; and a ternary nanocomposite coating layer of C-F-H formed on the buffer layer, wherein the ternary nanocomposite coating layer is formed by supplying reducing hydrogen in addition to C and F components during the formation process, wherein the coating layer is a gradient coating layer comprising a higher concentration of the F component toward the surface, wherein the coating material has a contact angle of 90 or more, and has a high hardness characteristic of 17 to 27 GPa. 2 . The coating material applied to a roller in secondary battery electrode manufacturing equipment according to claim 1 , wherein the coating material exhibiting the adhesion resistance has a low friction coefficient of 0.12 or less and a bonding force of the coating material of 20 N or more. 3 . The coating material applied to a roller in secondary battery electrode according to claim 1 , wherein the coating material exhibiting the adhesion resistance has an electrical resistance of 1 10 6 to 9.9 10 8 .
