Introduction to the electroplating industry
The market value of electroplating
Electroplating is a surface treatment process used to improve and enhance the durability, wear resistance, corrosion resistance, and aesthetics of the substrate. Due to the excellent functionality of electroplating, it is widely used in the automotive industry, electronics industry, medical industry, aviation industry, defense industry, and many other industries. As a result, electroplating is almost ubiquitous in our daily lives, and this has created a market value that cannot be underestimated. It is expected that by 2027, the market value of the global electroplating industry is expected to reach 21.9 billion U.S. dollars, and grow at a compound annual growth rate of 3.4% per year.
How does electroplating work?
Electroplating has a long history of development, and there are many different electroplating methods depending on the plating layer and substrate. We can divide electroplating into wet electroplating and dry electroplating according to the type of process. Among them, the wet electroplating process is more mature, its cost is relatively low, high temperature or high vacuum system conditions are not required, and it is suitable for mass production. The wet plating process can be divided into electrolytic plating and electroless plating (Electroless plating), the following is a brief introduction to the two process methods:
Electrolytic plating process:
Electrolytic plating usually refers to a process in which the anode and cathode reaction, used to convert the metal of the anode into metal ions in the electroplating solution and dissolve, and then diffuse to the surface of the cathode to be plated to make it adhere and deposition. If the anode used is a metal-free plate, additional metal ions to be plated must be added to the electrolyte.
Electroless plating process:
Electroless plating, also known as autocatalytic plating, is a process that uses the autocatalytic reaction of the metal to produce metal deposition on the surface of the substrate through its redox effect. This process requires the use of a reducing agent to provide the metal ions with electrons required for reduction so that the metal ions in the electroplating solution can accept electrons and be reduced to the substrate.
Why use electroplating additives?
When it comes to electroplating, we have to mention electroplating additives that make the quality of electroplating more stable. Many researchers will use electroplating additives in the electroplating process, and the role of electroplating additives depends on their function and the material to be plated. Common applications include carriers, brighteners, and leveling agents. The main functions are in optimizing the effect of electroplating, improving the electroplating rate, the uniformity, and brightness of the coating., etc.
