Description

Technical Field

[0001] The invention relates to the field of conductive systems, and in particular to an electroplated conductive component. Background Art

[0002] Electroplating is a process that converts electrical energy into chemical bond energy to form a coating on the surface of a material. In this process, materials with good conductivity and heat dissipation are usually considered preferred, and copper is often considered due to its excellent conductivity and heat dissipation properties. However, copper conductive parts face the following challenges in practical applications: First, insufficient corrosion resistance: copper has poor corrosion resistance in acidic and alkaline environments, which limits its application in certain corrosive environments; second, strength requirements are difficult to meet: in some occasions requiring high-strength support or load-bearing, pure copper may not meet the strength requirements, and additional reinforcement measures or the selection of other materials are required; finally, the cost is high: copper, as a precious metal, is relatively expensive, resulting in increased production costs, which is a disadvantage for scenarios with strict cost control requirements.

[0003] In view of the above-mentioned shortcomings of copper, steel materials (such as stainless steel, 45 steel, 42CrMO alloy steel, etc.) have become alternatives for conductive parts that need to meet the requirements of load-bearing, acid and alkali corrosion resistance, and good electrical conductivity. However, the thermal conductivity of steel (iron) is much lower than that of copper, only about 1 / 7 of that of copper, which makes it easy to overheat locally during the electroplating process, thereby causing the risk of oxidation and melting. In addition, the resistivity of iron is about 6 times that of copper, which may lead to poor conductivity when the conductive cross-sectional area is limited. When the conductive parts have poor conductivity, significant heating will occur locally. Due to the low thermal conductivity, the local temperature will rise sharply, resulting in a sharp drop in mechanical strength and even fuse failure. This not only shortens the service life of the conductive parts, but may also cause serious waste of resources and safety hazards.
