The word "electrochemical deposition" refers to the process of depositing metal ions onto a surface using an electrical current. It is spelled "ih-lek-troh-kem-i-kuhl dih-puh-zish-uhn." The first syllable is pronounced with a short "i" sound like in "sit," followed by the "lek" sound like in "peck." The next syllable is pronounced with a long "o" sound like in "toe," followed by the "kem" sound like in "gem." The final syllables are pronounced as "i-kuhl" with a short "i" sound, and "dih-puh-zish-uhn" with the "sh" sound like in "shoe."
Electrochemical deposition refers to a process in which a substance is deposited onto a surface through an electrochemical reaction. It involves the deposition of a solid material from an electrolyte solution onto an electrode (cathode), which serves as the substrate for the deposition. This technique is widely used in various fields such as material science, nanotechnology, and electrochemistry.
The process of electrochemical deposition is based on the principles of electrolysis, where an electric current is passed through an electrolyte solution containing ions. The ions are attracted to the electrode with opposite charge (cathode), where they undergo reduction reactions and form a solid layer on the surface. This solid layer is the deposited material, and its composition and morphology can be controlled by adjusting various factors such as the electrolyte concentration, current density, and deposition time.
Electrochemical deposition offers several advantages over other deposition techniques. It allows for precise control of film thickness, uniformity, and composition, making it suitable for applications that require thin and functional coatings. Furthermore, the ability to deposit a wide range of materials, including metals, alloys, and composites, makes this technique highly versatile.
This process finds extensive use in various technological applications, such as semiconductor fabrication, electroplating of metals, production of solar cells, fuel cell electrodes, and electroforming of high-precision components.
The word "electrochemical" combines two root words: "electro" and "chemical".
1. "Electro" comes from the Greek word "ēlektron" meaning "amber" or "electron". It is believed that the word "ēlektron" was used to describe amber because amber has the property of generating static electricity when rubbed. In modern usage, "electro" refers to electricity or electrically related phenomena.
2. "Chemical" comes from the French word "chimique", which was derived from the Medieval Latin word "chimicus" and the Arabic word "kimiyā". "Kimiyā" was a term used for alchemy, which was an ancient practice focused on the transformation of substances. "Chimicus" denoted a substance extracted by alchemy.
