Abstract
A wire for an ignition coil assembly and/or a corona ignition assembly is provided. The wire comprises a wire core including a copper-based material, and a coating applied to the wire core. The coating includes at least one of a carbon-based material and magnetic nanoparticles. The carbon-based material can include graphene and/or carbon nanotubes, and the magnetic nanoparticles can include graphene and iron oxide (Fe3O4). Typically, the coating includes a plurality of layers. For example, the coating can include a layer of the graphene and/or carbon nanotubes, and/or a layer of the magnetic nanoparticles. The coating can also include a layer of insulating material, such as enamel. According to another embodiment, the coating includes iron, nickel, and/or cobalt plated onto the wire core.
