Electroplating is a very useful process. It is widely used in industry for coating metal objects with a thin layer of different metals.
We list below some practical applications for which objects/articles are electroplated :
We all have seen the shining handles of bicycles and bath taps which are otherwise made of iron. This is done by electroplating them with chromium or nickel. Similarly, articles of base metals are often coated with precious metals to make them look more attractive.
We often find a chromium plating on bath taps, car bumpers, bicycle handles, towel rails, kitchen gas burners, wheel rims and so on. The chromium deposit not only provides a shiny appearance but also helps to avoid corrosion and scratches.
We know that some of the metals like gold, silver, platinum, nickel and chromium are very expensive. But artificial jewellery is often made by electroplating gold or silver on less expensive metals.
Electroplating is used for coating a thin layer of expensive metals like gold, silver on the cheap metals to give attractive look to the final product.
It is used in the area where we can reduce friction by coating certain kind of metal over the other.
It helps to protect from radaiton, abrasion and many other natural phenomenon just by imparting different metal layer on the surface.

It was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
Abhyas is a complete education Institute. Here extreme care is taken by teacher with the help of regular exam. Extra classes also conducted by the institute, if the student is weak.
My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
Being a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.
My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
It has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
It was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
