nickel plated aluminum a356 t51

Sep 30, 2010· We build sensors of T6065 aluminum and have them nickel plated. One was returned from central Florida with many spots of white corrosion, which appear under a microscope to be growing from a small point where the plating may have been pitted. But since aluminum forms an oxide layer so quickly, and the oxide is not soluble, how can the aluminum

The nickel coating is anodic to the Al substrate, similar to tin plate on steel. Once the coating is broken (pore/scratch, etc.), the substrate is.1Nickel is cathodic to aluminum and a breach in the plating will lead to rapid corrosion of the aluminum. I have seen aluminum components with elect.2swall is correct, nickel is cathodic (aluminum is anodic) in this couple.

Dec 23, 2005· There is two types of Nickel Plating. regular Nickel plating using electricity, or "Electroless Nickel" (called EN ) you can EN Aluminum parts, but it requires an extra process to kill the "Smut" (black soot) that occurs with Aluminum. Platers do not care about weight. They look at 5 things after you determine what you want in EN.

Nickel is an important element because of its positive effect on hardenability. Many important low-alloy steels contain nickel for this reason. Nickel, being a substitutional element in the iron lattice, has a small effect on increasing yield strength. Nickel, being an austenite stabilizer, is also a vital element in austenitic stainless steels.

Aluminum can be plated by applying an initial immersion zinc coating, followed by conventional copper-nickel-chromium plating procedure similar to that used for plating zinc metal/alloys. Protection against environmental corrosion for aluminum die castings is achieved through painting, anodizing, chromating, and iridite coatings.
