Electroless Nickel Plating is the deposition of a nickel-phophorous alloy onto a metal substrate without the use of an electrical current. The electroless nickel plating process utilizes an autocatalytic chemical reaction to deposit a reliable, repeatable coating of uniform thickness.
6 | GUIDE TO NICKEL ALUMINIUM BRONZE FOR ENGINEERS Broadly, the nickel aluminium bronzes can be classified as alloys containing 13% aluminium and up to 7% iron and 7% nickel. The more common alloys normally contain 6% each of these two elements. Manganese up to approximately 1.5% is also added, both as a deoxidant and a strengthening element.
corrosion is a multi-phased process that can sometimes result in secondary chemical agents that are as damaging as the corrosion itself. Hydrogen evolution is a good example of this. While corrosion is the main culprit, the resultant processes further weaken metallic components. Likewise, the corrosion resistance properties of various metals
