There are many, many items in our homes that benefit from the process electroplating. It’s a good job that we do electroplate so much because if we did not then a large amount of your utensils and cooking materials would just be a rusty mess at the back of your kitchen drawer. Take Electroless Nickel Plating. For example. It is an excellent way of protecting a product by totally coating it totally in the metal.
With this can of protection the subject is almost impervious to moisture and rust. Ideally it keeps both away as moisture and oxygen are the primary drivers of rust in metal. Nickel is an excellent metal to use as it barely rusts, if it all.
When you consider what the metal has to do when under stress you can see why it needs to be plated. For the most part the devices that are covered involve manufacturing moulds, tools for machinery (which are subject to a lot of use and abuse). They are also involved in the making of medical moulds for internal devices or something that is constantly required to move at high speed like a spindle.
