Explore New Advancements in Electroplating
Electroplating is a method of coating the surface of a metal or nonmetal object with a layer of another metal using electrochemical means to exploit distinct parameters and properties of the material. Electroplating can unite suitable properties of specific metals with different substrates.
The process of electroplating helps in the improvement of properties, appearance, and parts of the electroplated object. Before now, the electroplating method involved using metals on another metal. But, the world is advancing, and the new technology involves improving nonmetals with the same process.
Electroplating combines properties, including abrasion, electrical conductivity, strength, appearance, resistance, and corrosion. Also, the purpose of electroplating is to enhance the property of an electroplated material, whether plastic, wooden, or metal. Read further to explore current electroplating improvement.
What Are the Components of an Electroplate?
Electroplates have different components that support the process of electroplating. They include the following:
- Cathode: They are negatively-charged electrodes of electrochemical cells. Since reduction occurs here, the cathode holds the substrate material for the plating process.
- Anode: They are positively-charged electrodes of an electrochemical circuit. The anode holds the metal for the plating process.
- Plating Solutions: They are metal-finishing products that function as a catalyst to increase current flow into the device or circuit. A plating solution contains sulfates of copper and a few more sulfuric metals.
- Power Source: They add the flow of electricity to a cell. They are also responsible for introducing current into a device when they connect to an anode.
What Are the Types of Electroplating Processes?
There are various types of electroplating methods that you can use when coating a metal or nonmetal material. These include:
Rack Plating Process
The rack plating process involves the substrate remaining in a specific area. This process might not permit freedom or movement like the barrel plating process, as it depends on utilizing metal racks.
Engineers attach metal racks to the substrates using wires, spring fingers, or screws. The outcome of rack plating is that the electroplated material remains unmovable when immersed in the molten substance or electrolyte.
Barrel Plating Process
Barrel plating is a method that involves the rotation of the property inside the barrel. The substrates tumble and facilitate an equivalent layering of the electroplated material. Engineers utilize this electroplating method to achieve more advanced corrosion resistance and enhance the appearance of a metallic property.
Reel to Reel Plating
Reel to reel plating process is both practical and less expensive. It is a specialized method of plating that permits the removal of metals on underlying layers. Engineers use reel-to-reel plating methods for plaiting manufactured materials or designed products.
What Substrates Are Appropriate for Electroplating?
Engineers do not use just any metals they come in contact with. The electroplating process uses one metal or a combination of a few metals. The following are common materials that are suitable for electroplating:
- Zinc: They have high wear and tear resistance; therefore, engineers can combine nickel and zinc alloyed during electroplating to improve mental resistance to corrosive elements in the atmosphere.
- Palladium: They are corrosion resistant; engineers use them to improve metal hardness.
- Copper: Copper enhances the adhesion of substrate layers. Engineers achieve this by increasing copper substrate, resistance to conductivity, and heat.
- Tin: They are affordable and environmentally friendly substrates resist contact wear and tear. Tin plating is also the most malleable when in use.
- Silver: Silver plating is a finishing product with high malleability and ductility. It appears pleasant and resists corrosion. You can use silver to improve thermal and electrical conductivity.
- Gold: Gold plating has to be the most precious metal with an excellent aesthetic appeal. It permeates substrates with tarnishes, high conductivity, wear, and corrosion resistance when in use.
