seminar on electroplating
Answers
electroplating is the process of coating a metal for an alloy with another metal using the process of electrolysis . electroplating is necessary for making articles look attractive as well as for protection against corrosion . nowadays people prefer to buy gold plated jewelry . similarly , iron articles are often coated with Nickel for chromium to protect them from rusting and corrosion . carry out the process of electroplating the object to be electroplated is cleaned and made the cathode . the metal used for electroplating is made the anode of the electrolytic cell. for example if copper is being you said to Court another substance and electrolytic solution containing copper ions should be kept in the electrolytic cell . all the copper ions will be attracted towards the cathode where the object is placed and the object will get coated with copper
Electroplating is a process of coating a metal by another metallic meterial in an electrochemical bath by using the process of electrolysis.
OR
The complete process of coating a metal on another material by electrolysis process is called electroplating.
Electroplating is also used to avoid corrosion of steel object .
Coating the surface with metal like tin, chromium, nickel, etc by electroplating is also utilised to prevent corrosion.
Steel cans are protected by coating them with relatively unreactive tin. It works well as long as the thin tin layer is intect.
