Electroplating metals questions

What are two practical uses of electroplating and why do we electroplate metals. What are electroplated metals used for.

Hi, Nafateeri. There are a half dozen different electroplated metals in the computer you just typed your question into -- including copper, nickel, tin, gold, and usually some silver, palladium, and chromium. Some of this electroplating is used for carrying current, some is for corrosion resistance, and some for decorative reasons. So two practical uses for electroplated metals are to allow you to play video games and post your homework questions :-)

There's a starting point, and I suggest you continue your research at the library. Good luck!

can you please tell me of some specific applications for engineering in regards to electroplating?

There are countless examples, Josh M --

Some alloys can be created only through electroplating rather than by mixing molten metals.
Components of certain types like ultrafine screening and hollow gold jewelry can only be made by electroplating.
Electroplating also allows us to make parts of strong flexible materials like steel, while having surfaces of hard brittle materials like chromium or nickel-diamond composites so that we can have molds and cutting tools and machine parts and truck bumpers that will wear well while not being subject to fracturing.

Take these terms and concepts to the library and see what you can dig up. Good luck!

Hi, my name is Josh from Hollister Ca. and I was just wondering what are some benefits of electroplating an item with a metal?

I am a senior student from the Bahamas, wondering if you would be able to give me a detailed list of apparatus required to copper plate an object. I've found bits and pieces, including some on this website, but things such as how much vinegar to use, how much salt, etc, are not specified. I would appreciate this information, as it will allow me to complete a chemistry project.

Hi, Treat. We give you a good idea on this stuff in our FAQ: "How Electroplating Works".

You should use full strength vinegar (it's already a very mild acid, no sense in further diluting it). Add just a pinch of salt (we explain why in the FAQ). But remember that this demo is just to show you the principals; it isn't really a practical way to electroplate (practical electroplating requires proprietary and toxic chemicals).
