        History of Electroplating Technology

        History of Electroplating Technology


        In 1805, Italian chemist Luigi Valentino Brugnatelli pioneered the modern electrochemical process. Brugnatelli cites his colleague Alessandro Volta's 1800 invention of a photovoltaic reactor technology, the first electrodeposition process in history. But Brugnatelli's invention was suppressed by the French academy of sciences and was not widely used for the next three decades. By 1839, British and Russian scientists had independently designed a Brugnatelli process for depositing metals and electroplating copper. After that, Boris Jacobi developed electroplating, electroplating and electroforming sculptures in Russia, and electroplating technology came into public view.

        In the 19th century, the electroplating industry got great development opportunities because of the emergence of generators. As the current applied to electroplating increases, metal machine parts that need corrosion protection and wear resistance enhancement can be mass produced, while hardware and automobile parts can achieve better appearance. Since then, two world wars and the growing aviation industry have stimulated further development and improvement, including hard chrome plating, bronze alloy coating, nickel sulfamate coating and many other electroplating processes. Electroplating equipment is transformed from manually operated tar wood boxes into automatic equipment capable of handling thousands of kilograms of parts per hour.



        Before talking about electroplating technology, science students will give you a brief introduction to the principle of electroplating. Any substance in the world is made up of atoms. When atoms exist alone, they are not charged. Especially pure metal substances, they are all closely combined by atoms. When metal dissolves in solution due to electrochemical action, the metal atoms will lose electrons to form metal ions, and then the metal will be positively charged. Since we were young, we have known the axiom that the same sex repel each other and the opposite sex attract each other. Therefore, when the surface of the object to be electroplated has a negative point, the positively charged metal ions in the solution will be attracted to it. When the positively charged metal ion contacts the negatively charged surface of the coating, the metal ion will get electrons and form metal atoms. At this point, due to the intermolecular force, the metal atom and another conductive atom on the surface of the plating are closely combined. A coating is formed when thousands of metal atoms are tightly bonded to the surface of the substrate. And one of the principles that's particularly important in this process is the concept of volt electric reactor technology, which may be a little bit strange to you, but it's the principle of batteries.



        We know that water conducts electricity, and electrolyte solutions do even better. When the electrolyte solution is electrified, the entire circuit is actually in a path. In this way, the two points in contact with the electrolyte can absorb and release electrons respectively, thus making the situation of gaining and losing electrons of the metal ions above hold true. The friend that learns chemistry can think of immediately, this is electrolytic pool principle.
