NOVELTY - The utility model claims an inductance coil with good toughness effect, comprising a magnetic core, the top and the bottom of the magnetic core surface are sleeved with a flexible coil main body; the top of the flexible coil main body is coated with an anti-corrosion layer; the anti-corrosion layer comprises an epoxy zinc-rich primer layer, acrylic acid coating layer and polyurethane coating layer; the bottom of the magnetic core is coated with a heat conducting layer; the heat conducting layer comprises a graphene coating layer and a ceramic coating layer; the graphene coating layer is located at the top of the ceramic coating layer. The utility model through the magnetic core, a flexible coil main body, a heat conducting layer, a graphene coating layer, a ceramic coating layer, an anti-corrosion layer, an epoxy zinc-rich primer layer, acrylic acid coating layer and polyurethane coating layer are matched to use, reaching the advantages of good anti-corrosion effect, solving the problem that the existing inductance coil has bad anti-corrosion effect when using, often there is corrosive liquid, so that the inductance coil will be damaged, so the problem of affecting the service life of the inductance coil.
