Just like my very popular copper plating instructable, the aim of this is to do high quality, low cost, and safe electroplating. We will also be making our own electrolyte from scratch instead of buying chemicals online.
If you've looked at my copper plating instructable, note that the process here is different. The nickel will not dissolve very well if at all in the vinegar without special help and adding hydrogen peroxide will destroy your electrolyte.
Nickel plating can be used for a variety of different things.
- It creates a corrosion resistant coating that will protect the base metal from oxidizing and rusting. It is frequently used in food processing to prevent contamination with iron.
- It can increase the hardness and thus the durability of mechanical parts and tools.
- It can allow you to solder to difficult metals.
- It can create a variety of beautiful decorative finishes that range from a chrome-like gleam, to brushed stainless steel color, to a metallic black. It just so happens that black nickel plating is used frequently in aerospace applications
- In thicker platings, it can make the object magnetic.
Note that to get different finishes and properties, you may need to add other chemicals and metals to your plating solution (see the Post Prep stage). These chemicals will change the way the atoms arrange themselves and/or add other metals to your plating. If you are looking for corrosion-resistance, do not add any other chemicals to your electrolyte as they may cause the end plating to stain or tarnish.
For a copper plated finish, be sure to check out my copper plating instructable :) http://www.instructables.com/id/High-Quality-Copper-Plating/ On another note, I LOVE your questions! I have noticed that a few folks are asking the same questions, so I've added a "Common Questions" step/slide/section/whatchamacallit at the end of this instructable. Take a look there to get quick answers to most of the questions you might have. If you have a new one, comment below and I'll be happy to answer it and add it to my step/slide/section/whatchamacallit :D
A quick disclaimer - nickel acetate, the chemical we will be making, is poisonous. The title "High Quality (and Safe) Nickel Plating" is referring more to the fact that you don't need to play with insanely powerful acids that will burn your skin or ask you to open batteries. In the concentrations we will be working with, the process is fairly safe. However, do NOT drink the solution and be sure to wash your hands after plating and properly wipe down any surfaces that come near or into contact with your plating solution. Always supervise kids. That said, enjoy!
