The Copper alloy has excellent electrical and thermal conductivity as well as good strength, toughness, and fatigue resistance, and is therefore widely used, for example, in various continuous casting molds, blast furnace slag holes, oxygen nozzles for converters, and so on. Among them, the C17200 copper alloy has very good strength and electrical conductivity and is popular for its easy processing and non-magnetic properties. C17200 copper alloy is widely used in contact components such as conductive brushes and rolled rings because of its very good elastic properties. However, because of the low hardness of these alloys, they are susceptible to adhesion and abrasive wear, so it is essential to improve their tribological properties by preparing surface modification layers. This can be achieved by introducing other alloying elements into the surface to create intermetallic compound-modified layers.

Intermetallic compounds exhibit good properties such as high strength, low density, good oxidation resistance, and high-temperature performance. Recently, intermetallic compounds have gained much attention as good wear-resistant materials such as Ti-Al intermetallic compounds, Ni-Al intermetallic compounds, Ni-Ti compounds, Mo-Si compounds, and Fe-Al compounds.
