Electroplating

The plating current is charged with the material that seeds with one or more layers of solution (cathode) that is applied to the metal member by the method of charging by the current containing negatively positive dissolution metal ions (anode)

Dating back to the ancient Egyptians, they are painted with gold metal and nonmetal or process called "gold plating", this is the first known surface treatment. Although some metals more consistently made of other metals, the use of electrical means flows easier deposited metallic edge members or high current areas. Attempt to complex shape or internal part or member ID plating, if this trend is particularly prominent

In addition to that single metal, you can also simultaneously tin and lead alloy coating, zinc, iron and other materials can be plated to obtain the desired customization function

You may already know that plating is a common metal surface treatment / refinement process that can be used in many industrial applications. But you may not be used to how plating works. Plating is not new - the earliest incarnation of modern electroplating was actually in the early 19th century. Along with the development of industry and manufacturing industry in the past two centuries, the electroplating process has also evolved. This is a brief explanation of the mechanism of plating. Let's assume that a layer of gold is electrodeposited on metal jewelry and improves the appearance of the part. The plated metal or coating (gold) is connected to the anode (positively charged electrode) of the circuit and the piece of jewelry is placed on the cathode (negatively charged electrode). Both are immersed in specially developed electrolyte (bath)

Along with the development of electrochemical science, people gradually understood the relationship with electroplating and developed other kinds of non-decorative metal plating. Commercial plating of nickel, brass, tin and zinc was developed in the 1950's. Electroplating tanks and equipment based on the Elkingtons patent are enlarged to accommodate the plating of many large objects as well as specific manufacturing and engineering applications. Due to the development of generators in the latter half of the 19th century, the electroplating industry was greatly encouraged. Because higher currents are available, metalworking machine parts, hardware and automotive parts require corrosion protection and enhanced wear performance, as well as a better appearance that can be processed in batches.
