Scientifically, electroplating can be defined as coating a conducting metal surface with another metal. Usually, a more expensive metal is coated on a less expensive material, like Gold on Copper. It is also used to prevent corrosion with the help of Zinc, a less corrosive material, is coated on top of the corrosive material. Electroplating can alter appearances, protect, add sheen and give engineering and mechanical properties to the metals.
The drawbacks of electroplating include
- A uniform thickness is hard to achieve.
- The electroplating becomes more complex as the geometry of the object increases in complexity.
- It involves a high initial investment.
- The electrolyte solution, once used, becomes an environmental hazard, causing pollution.
- Safe disposal methods of the electrolyte are currently unavailable.
These disadvantages are overcome at Electroplating in India.
Nickel has established for itself a reputation that it is very “flexible”. It is used to increase the value of the metal over which it is coated. It is silvery white. This adds to sheen and luster of the articles. Sometimes, articles are subjected to electroplating only after primary coating with nickel. In Chrome-plating, metals are first subjected to Nickel coating before subjecting them to Chromium plating. They are renowned for their anti-corrosive, anti-absorptive, anti-emissive, anti-reflective lustrous and magnetic properties. Nickel surfaces have been used in the mu-metal finishes. There are two types of electroplating.
- Electro-plated
- Electroless
Nickel Plating in India has succeeded in offering the best quality plating. They are used for their physical properties. There are reduced worries regarding the unevenness of the surface. The nickel coating done in the engineering tools is nicknamed as heavy or thick nickel. They can withstand heavy wear and tear. They can also show improved corrosion resistance. The biggest plus of Nickel plating is that it can make a cheap metal look like an expensive artifact.
Renamed as galvanization, Zinc plating is application of Zinc over another metal, particularly steel. The longer the zinc plating process, the thicker the Zinc layer coated on the metal. Zinc primarily protects the metal by taking on the role of a martyr. When the agents of corrosion come across the metal, Zinc faces the wrath of the agents and gets degraded slowly. This is not a permanent remedy. Zinc plating is said to only to delay the corrosion. The coating of Zinc as an alloy along with iron is found to produce a thicker coating. The coating can be done in a very clear type. This is called as Type A Plating. Here very slight iridescence and the coating is almost transparent. Zinc Plating in India offers the best plating processes to suit your every need. Zinc Plating is usually done on cheap merchandise.
