We try to use nickel plating on our aluminum part (6061 or 5052) for corrosion protection. But the position between nickel and aluminum in Galvanic index (anodic index) is quite far. If a galvanic corrosion will happen between them. Normally electrode reaction occurs when water or other electr...
Aluminum alloysAustenitic stainless steelBiofilmsBronzeCathodesElectThe galvanic corrosion of the alloy UNS<1) C95800, referred to as Nickel Aluminium Bronze (NAB) has been investigated in natural seawater under the influence of a magnetic field (MF). NAB was coupled to the austenitic stainless ...
Material formulation for galvanizing equipment submerged in molten and aluminum zinc melts An article suitable for submergence in molten zinc, aluminum and aluminum/zinc melts. The article is formed of an alloy comprising from greater than 1.0% to less than 5.0% carbon; from greater to 10.0% to...
Murray Raney in the United States developed in 1926 the selective leaching process to obtain a finely grained nickel–aluminum alloy from a quenched melt of nickel and aluminum leached in concentrated sodium hydroxide. The “Raney nickel” alloy shows high catalytic activity with a wide application ...
Nickel layers can be applied to all commonly used pure metals and alloys. Substrates include: Unalloyed and low alloyed steel Copper and copper alloys Brass Zinc and aluminum alloys Plastics Before nickel plating a substrate, it must be free of ...
The coating is more noble than steel, and therefore it has to be virtually without pores or cracks. To have goodcorrosion resistance, the coating thickness should be about 30μm and should have a high phosphorous content. Electroless nickel is widely used forcorrosion protectionofaluminumand ...

Chromic Acid Flake Contemplating how to continue offering chromic acid services in an increasingly stringent regulatory world? Liquid chrome products...
. Right now, our product will be exposed to the harsh environment. In this situation the silver plating is going to change the color to black (corrosion). It looks terrible. We need some kind finish which is much more stable than silver plating, but solderable on substrates of aluminum....
aluminum andaluminum alloysis disclosed in US Patent No. 4400415[6]. The process involves steps of electrolytic orelectroless plating, coating a layer of nickel by immersing the substrate in a hydroxide solution that has a pH of approximately[12]or above, and dissolving a nickel orcobalt ...
Nickel Aluminum Bronze (NAB) and Manganese Aluminum Bronze (MAB) are high-alloyed bronzes that are increasingly employed in several industrial sectors, mainly related to hostile environments due to their excellent properties against corrosion, cavitation, erosion and improved mechanical properties in relati...
