what is electroplating
consideration. Cathode:The cathode in the electroplating circuit is the part that needs to be plated. atoms from the plating metal bond to it effectively by joining very Electroplating is primarily used to change the physical properties of an object. This process is also known as electrodeposition. This part acts as the negatively charged electrode in the circuit. How Electroplating Works. copper-based compound such as copper sulfate solution. Despite the popularity of electroplating, however, very few outside of the industry are familiar with the process, what it is and how it works. Depending on how much wear and tear the plated part has to withstand, the coating can be anything from about 10–30 microns thick. China’s electroplating process is mainly zinc, copper, nickel, chromium plating, with50% of the zinc painting and 30%of copper, chromium and nickel painting, respectively. as you can see in the brownish area in the center of this pie server. When performing copper plating fill type is … metal, such as copper, with a thin layer of another, more precious All kinds of metals can Electroplating is also known as electrodeposition. of an adult) at home. of copper plate. Electroplating, also known as electrodeposition, occurs when electric current is used to coat the surface of a metal material. Electroplating involves using electricity to reduce a metal salt out from solution and deposit it in metallic form onto a surface, Rich. Electroplating is the deposition of a metallic coating onto an object by putting a negative charge onto the object and immersing it into a solution which contains a salt of the metal to be deposited. gold and silver don't easily dissolve so have to be made into You'll often find parts on cars, plumbing, household, and electrical fittings that look metallic but are, in fact, plated plastic. supply. Some of the specific benefits of electroplating include the following: Some benefits offered are metal-specific. Otherwise, when metal atoms from the electrolyte are deposited onto Of these, electroplating is the most prevalent for functional and decorative applications. They're lighter, cheaper, rustproof, and don't require any polishing after plating. This process can be used to give objects increased wear resistance, corrosion protection or aesthetic appeal, as well as increased thickness. Something like a gold-plated watch case would have a 20 micron coating that could easily last everyday rough It is also called the substrate. is a good substitute for many people. With SPC, you can trust us to provide experienced, customer-focused service from start to finish. need to be present in the alloy. In theory, that should completely rule out electroplating; in practice, it simply means we have to give our plastic an extra treatment to make it electrically conducting before we start. charged) are attracted to the negatively charged brass electrode often tin plated to make them resistant to corrosion, while many Emigsville, PA 17318, Electroless Nickel Immersion Gold Plating, Electroplating for Rail and Transportation, Common Applications of Nickel Electroplating, Electroless Nickel vs. The idea is to use electricity to coat a relatively mundane All these things are examples of There are several different plating techniques available, each of which can be used in various applications. gold-based electrolyte—and so on. This process results in a thin layer of metal being deposited onto the surface of a workpiece called the substrate. The Microsmooth™ process uses about 30 percent less electricity, nearly 60 percent less natural gas, and half the water that conventional plating processes need. Some of these are detailed below: With our extensive experience in a range of industries, SPC can assist with these electroplating applications and more, offering a range of cost-effective plating services. circuit with a battery or other power supply. Zinc-nickel alloys, on the other hand, are used to prevent the formation of sharp protrusions during manufacturing, which can result in part damage. Whether your company is looking for corrosion protection, improved durability or increased electrical conductivity, electroplating offers solutions. The coating applied by electroplating is usually around 0.0002 inches thick. becomes the negative electrode (or cathode). This is done by dipping two terminals called electrodes into the electrolyte and connecting them into a circuit with a battery or other power supply. Copper ions (which are positively Sign up for our newsletter or contact us to learn more about our plating and metal finishing solutions. Electroplating definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. it, they won't form a good bond and they may simply rub off again. SPC has over nine decades of experience in the industry, developing a wide range of cost-effective plating and metal finishing processes to suit the needs of companies across numerous industries. An acid electroplating solution is a mixture of water, acid, and the metal to be plated. electrolyte, so if you want to copper plate something you need an electrolyte with chromium to make them both attractively shiny and Next, it's etched with acid and treated with a catalyst (a chemical reaction accelerator) to make sure that a coating will stick to its surface. For example, nickel plating is useful for reducing friction, which helps to reduce wear and tear and improve part longevity. All of these industries favor electroplating for its functional capabilities, as well as its low cost and flexibility of application. be plated in this way, including gold, silver, The object is then immersed in a salt … charged) arrive at the positively charged copper anode, releasing electrons "EPNS" marked on cutlery is a definitive Some of these types of electroplating are described in more detail below: While these methods accomplish electrodeposition in different ways, they all use the same basic principles. electrochemistry: chemical reactions caused by or producing strongly onto the outside edges of its crystalline structure. When used in the jewelry process, it can enhance the aesthetic value and wearability of a piece. making duplicates of printing plates in a process called Inexpensive, easy to form into different shapes, lightweight, and disposable, plastics rapidly became the world's most commonplace and flexible materials in the 20th century. protective outer later. Electroplating serves as a functionally and financially beneficial option for a variety of applications, but you need to partner with the right plating company to see all the benefits. widely made from tough steel plated Usually the metal which is being plated is different than the metal of the substrate. What is Electroplating? Because different metals are different colors, Box, 157 3315 Connelly Rd. Electroplating (often just called "plating") is the deposition of a metal coating onto an object by putting a negative charge on it and putting it into a solution which contains a metal salt. zinc (in a process called galvanization) for the same reason. It takes time for electroplated atoms to build up on the surface of the negative electrode. made from a solution of a copper salt, while for gold plating you need a Once that's done, it can be electroplated just like a metal. Electroplating is the process of plating various metals onto a metal or plastic part. Electroplating is the practical application of electrolytic cells.
