Aug 07, 2008 Yes almost all alloys of aluminum can be nickel electroplated. You need a good pre-cleaning process sequence that includes non-silicate base alkaline cleaner, nitric+hydrofloric acid zincating solution. There are many zincating solutions available in the market for this. K.Ramesh - Mumbai, India ^ publicly reply to K.Ramesh ^

But we ha...Getting "Nickel Oxide" Coating on Large Aluminum SheetsQ. What would be the best way to get a "Nickel Oxide" coating on large aluminium sheets?Q. Hi Folks I'm hoping that your vast experience and knowle...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.
Dec 27, 2021 At 500 °F you will have a thermal expansion problem. For the anodized aluminum the underlying aluminum alloy will expand 5 times the expansion of the anodic film. At 0.002" this could be a problem. Hopefully an EN expert will comment on the expansion of EN over aluminum.
May 23, 2019 For smooth cast aluminum parts, anodizing provides an aesthetic finish since anodizing can be done in a clear coating as well as a multitude of colors, which can definitely be an attribute in favor of anodizing. Nickel plating is more versatile, and still almost always looks good, that is if you don't mind the extra weight added to the part ...
预计阅读时间：4 分钟Apr 07, 2007 To answer your question, nickel plating would "posion" the anodizing bath, and anodizing would prevent nickel plating. So both would require the same amount of masking, but anodizing first would be safer, as the only result of a bad mask would be incomplete plating, where the nickel plating in the anno bath could cause burns in the aluminum.
Plating on Aluminum Chrome Plating and Electroplating Aluminum. Aluminum is both light weight and high strength. Aluminum plating is ideal for use on motorcycles, automobiles, and aircrafts.. Aluminum castings, extrusions, forgings, and machined billet can all be decorative nickel chrome electroplated to improve the appearance and enhance the corrosion performance.
Our aluminum chromate alodine aluminum services comply with the chemical film Mil-DTL-5541, Mil-spec standards, and can withstand an ASTM standard salt spray test for 168 hours. Aluminum chromate conversion coating/alodine produces a thin coating in the range of 0.00001-0.00004 inches (0.25-1.0 µm) in thickness.
Jan 06, 2013 "Cadmium plating over aluminum alloys with Electroless Nickel as Undercoat" 2003. Q. I looking to see if anyone knows what the thickness of cadmium with olive drab chromate over electroless nickel on aluminum are needed to pass 1000 hour salt spray. Any information provided will be very helpful. Thank you, Casey Stein - Tempe, Arizona, US ^
Oct 29, 2021 If you strip the anodizing, the diameter will be down to 0.9998". If you were to anodize the second time to a thickness of 0.0004", the diameter after anodizing would be 1.0002" again. So it might be theoretically possible to restore the original diameter by anodizing twice as thick the second time around.
