Talk:Electrogalvanization

Plagiarism and article duplication

This article is overlapping much with Zinc alloy electroplating, as some material is directly copied between them. In addition some of this appears plagiarized from commercial sites. This needs to be sorted out and reworked and possibly consolidated. Kbrose (talk) 13:07, 10 July 2014 (UTC)[reply]

False claim

The claim: ″Compared to hot dip galvanizing, electroplated zinc offers these significant advantages: Lower thickness deposits to achieve comparable performance″ is untrue, as the main reason to apply a zinc layer to a steel surface is to achieve a better corrosion protection (performance)... therefore this claim is false and tendentitious, and should be corrected. What is true, is that cosmetically speaking electrogalvanizing renders a somewhat better appearance finish, but never a more protective layer.

Your argument doesn't prove that the claim is untrue. Maybe this thinner electroplated layer has the same protective effect as a thicker, hot-dip applied one. I have no idea myself, really, but your opinion alone that it cannot be, is no proof. 194.174.73.80 (talk) 18:02, 22 August 2017 (UTC) Marco Pagliero Berlin[reply]

The main reasons it's used are that it doesn't distort complex assembled shapes (e.g. car bodyshells) with heat, or that pre-electrogalved flat sheet can be shaped and welded after plating (i.e. in repair garages etc.) whilst a hot-dipped sheet can't be welded strongly without first stripping the plating.

In many applications - and car bodies are the main ones - electrogalv is entirely adequate as rustproofing, because it's painted as well. Only for trucks with a separate chassis (of heavier gauge steel) is hot-dip used, after assembly. Andy Dingley (talk) 18:26, 22 August 2017 (UTC)[reply]

Not a zinc expert, but this summarization could relate to the 84Zn/14Ni subtype? There's a (granted, unsourced) claim further down the article that, in performing their protective action these coatings slowly approximate the corrosion potential of Fe, as their Zn content is preferentially leached. (All else being equal, a lower potential missmatch will result in a lower corrosion current and so a longer life for the remaining layer.) Without evidence to the contrary I'd leave the claim; if this really is the mechanism (especially if someone can provide a reference for that), the explanation might make good content in the article.

Electroplated "zinc" hardware is the cheapest finish at the hardware store. Electrogalvanized hardware that has received no paint or additional plating will rust in the first rain when left outside and is never rated for outdoor applications. In contrast, hot dip galvanized hardware is typically specified for outdoor applications. Antipattern3 (talk) 06:42, 25 April 2022 (UTC)[reply]

Language

This article is poorly written or edited, full of impossible sentences. It needs a thorough rewrite. Antipattern3 (talk) 06:46, 25 April 2022 (UTC)[reply]

Alkaline

Use the standard chemical term basic instead. Antipattern3 (talk) 06:46, 25 April 2022 (UTC)[reply]

ESCE

This term is introduced without explanation. Instead, link to standard potential. Antipattern3 (talk) 06:48, 25 April 2022 (UTC)[reply]
