Coating Structure Comprising Graphite Alloy and Preparation Method

Abstract

A coating structure includes a substrate, a first metal layer, a second alloy layer, a third metal layer, and a fourth alloy layer. The first metal layer is plated on an outside of the substrate and does not include graphite. The second alloy layer is plated on an outside of the first metal layer and is synthesized from graphite and metal. The third metal layer is plated on an outside of the second alloy layer and does not include graphite. The fourth alloy layer is plated on an outside of the third metal layer and is also synthesized from graphite and metal.
