Electroplating Method on Copper (Cu) Substrate with Silver (Ag) Coating Applied

Abstract

Knowing about metal coating (electroplating) is the electrodeposition of coatings or coatings attached to the electrodes to protect the substrate by giving surface properties and dimensions different from the base metal or finishing technique, by coating metal that is easily corroded (corrosion) with metals that are resistant to corrosion with electrical and chemical engineering. Whereas in Indonesian society the technique for metal coating is very familiar with the name of the gilding technique. In ancient times before electroplating and gilding were discovered to avoid corrosion of metals, the incorporation of metals such as copper with tin into bronze, copper with zinc into brass in addition to being resistant to corrosion also added to the beauty of color. Among the alloys above bronze is the oldest alloys that have been used by humans. With the development of the times, more modern gilding techniques were found to be a more practical method, namely electroplating, gilding with electrical and chemical processes that make metals resistant to corrosion. Metal coating is a scientific field which is one of the applications of electro chemical technology. Very closely related to the material science and technology, surface chemistry, physical chemistry, to the engineering. Various metals can be plating. The various metals are classified into five groups: "tumbal" coatings, decorative-protective coatings, engineered metal coatings, rare-use metals, and various types of alloys. All of these have their own characteristics, both advantages and disadvantages.

Material Test Comparison of Pure Aluminum (Al) and Pure Aluminum-Coated (Al) with Silver (Ag) Substrat Using Electroplating Method

“…Pure Al metal type with pure Al-coated acts as a cathode (connected to the electrical negative pole). The coating metal uses an Ag substrate which acts as an anode (connected to the positive electric pole) (Selly et al, 2020). Cu Plating has a function as a layer of copper (Cu) on Al metal.…”

“…This is strongly influenced by the distribution of electric current density. The thickness of the silver layer will not be uniform if the current density is not well distributed (Selly et al, 2020).…”

“…We refer to (Selly et al, 2020) for the electroplating process procedure. After doing the electroplating process, we tested for metal testing by used the Brinnell test method.…”

The Effect of Nickel Electroplating on the Surface Hardness of Low Carbon Steel

“…The basic principle of electroplating is the placement of metal ions plus electrons originating in the electrolytic solution of the coated metal. The ions are obtained from the anode and electrons from the electrolyte solution [3] and [4].…”
