Talk:Pickling (metal)

Merge from Pickle liquor
I don't think that pickle liquor needs it's own article, because it is only applicable to this article. There's no reason in splitting the idea. Moreover, both articles have a word for word identical paragraph about the disposal of pickle liquor. --Wizard191 (talk) 13:54, 28 August 2008 (UTC)
 * Support - I agree with your reasoning and see no reason to split at this time, if more information were to become available making the section on the liquor too long then the article could be split again at that time. Stardust8212 15:24, 28 August 2008 (UTC)

Pickling or tarnisioning?
I have no knowledge on the subject, but it is confusing that the title of the article is pickling, while everything else there talks about tarnision. This change was made at http://en.wikipedia.org/w/index.php?title=Pickling_(metal)&diff=prev&oldid=450455488 -- Petteri Aimonen (talk) 10:15, 29 December 2011 (UTC)


 * Using google scholar, I found no articles that had "tarnision," while there were 32,100 articles that had "acid pickling." Likewise, there are only 320 results for "tarnision" for Google search and 117,000 for "acid pickling." Also, many of the tarnision pages are actually copies of this Wikipedia article, not independent sources of information. Lakshwadeep (talk) 16:45, 3 April 2012 (UTC)

Details on EPS and SCS?
Reading the text, I am unclear as to the differences between the EPS and SCS processes. They sound so similar, both relying on mechanical methods to produce the desired effect. Some more detail on the specifics and advantages/disadvantages of each would be very useful. — Preceding unsigned comment added by 17.114.48.27 (talk) 21:27, 15 January 2014 (UTC)

Solution Formulas?
The article is called "Pickling (metal)", but I estimate that at least two thirds of it discusses peripheral matters: alternatives, disposal (eco) issues, etc. What about more details on the process itself? For example, solution formulas seem to be conspicuously absent. — Preceding unsigned comment added by 82.68.15.142 (talk) 15:25, 19 June 2014 (UTC)

How does pickling work?
In concurrence with prior comment on chemical formulas, it would be helpful to just have an explanation for what exactly happens when you pickle? Why do you use an acid? What excactly is the acid doing to the surface impurities / rust?

The page on Hydrochloric acid has a section that somewhat explains how HCl pickling works... https://en.wikipedia.org/wiki/Hydrochloric_acid#Pickling_of_steel. I'm going to add a link to that page, to at least inform people where to find a bit more of an explanation. SloppyG (talk) 01:45, 5 July 2019 (UTC)
