These chemicals will change the way the atoms arrange themselves and/or add other metals to your plating. To get different finishes and properties, you may need to add other chemicals and metals to your plating solution (see the Post Prep stage). It just so happens that black nickel plating is used frequently in aerospace applications - In thicker platings, it can make the object magnetic. 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 can allow you to solder to difficult metals. It can increase the hardness and thus the durability of mechanical parts and tools. It is frequently used in food processing to prevent contamination with iron. It creates a corrosion resistant coating that will protect the base metal from oxidizing and rusting. Nickel plating can be used for a variety of different things. The nickel will not dissolve very well if at all in the vinegar without special help and adding hydrogen peroxide will destroy your electrolyte. If you've looked at my copper plating tutorial, note that the process here is different. We will also be making our own electrolyte from scratch instead of buying chemicals online. Just like my popular copper plating instructable, the aim of this is to do high quality, low cost, and safe electroplating.
