Not all metals play well together. And this spills over in to the world of electronics and the materials used therein. A relatively new and relevant example came about with the advent of RoHS and the desire to identify a "drop-in" replacement for SnPb(Ag
reducing its strength and thickness. This type of metal corrosion is closely linked to phenomena like cracking paint. When two dissimilar metals come into contact within a corrosive setting, one metal undergoes galvanic corrosion while the other one maintains galvanic protection. ...
The corrosion behaviour of a dissimilar metal friction stir weld between AA2024–T351 and AA7010–T7651 was investigated. Gel visualisation and immersion tests were used to examine the effect of galvanic coupling between the two components. A microelectrochemical cell with a 400 μm diameter glass...
As the corrosion behavior of 6xxx series aluminum alloys depends on composition and microstructure, the microstructure and corrosion behavior of 6082 and a new 6xxx aluminum alloy weld joint are investigated under a standard corrosion test in this study. These results show the asymmetrical welding jo...

Dissimilar metals – Use of dissimilar metal causes galvanic corrosion. Knowledge of galvanic potential of materials and the Nernst equation to understand corrosion potential can be applied; this is helpful in this stage of design: E=E°−(RT/nF)×In[reaction products/reactants] Where: E = ...
39837/58. Class 123(1) Corrosion of contacting dissimilar metals, for example, aluminium alloys in contact with steel or steel soldered to brass, forming part of a system containing an aqueous medium, for example, a hydraulic power system or an I.C. engine cooling system, is minimised by ...
corroded due to rain getting between the dissimilar metals. There is a very small differential between these two metals. What staggers me is that in the UK the present motorway construction is for galvanised MS columns with the message board affixed by numerous Stainless steel bands. Stainless an...
