Stray Current Corrosion

Is there a reason that stray current corrosion, such as what occurs when DC from a railroad system corrodes nearby metal objects, is not mentioned in this page? it seems a logical topic to have been covered. — Preceding unsigned comment added by 192.212.247.98 (talk) 17:04, 14 February 2012 (UTC)

Corrosive hazard

The corrosive to human tissue hazard should not be conflated with electrochemical theory. Corrosive should not be a redirect to corrosion. --Vuo 20:35, 2 April 2007 (UTC)

corrosion is also held in metals and nonnmetals.....

I just reverted a section added by user_talk:71.38.130.247. Their attempt was to add a section on the common occurrence of corrosion (bikes, fences, etc.), a section I feel would help strengthen the article and help relate the topic to the less-knowledged common reader. Obviously, it should be referenced and written in an encyclopedic manner, which is why I reverted the section. Anyone have any feelings on this proposed section? —Brien Clark^Talk 04:53, 18 April 2007 (UTC) i think that you should put back the section for now as the usefulness might outstrip the need to be faithful to encyclopedic form.

Corrosivity?

Hi there! I was wondering if there is a term such as 'corrosivity'. Seemingly it doesn't exist (only 149k google hits, not listed in any online dictionary or thesaurus, only a redirect to this page on en.wikipedia...) but it's intended to describe the corrosive activity of a substance. E.g. the different effects of highly concentrated (88%) and diluted (30%) sulfuric acid on, say, a metal surface show that the corrosivity of the latter is much higher than of the former (I reckon this is about the HO3+ content or sth). Anyways, I am pretty sure that there is a matching notion for this feature only I don't know it. Please help a desperate German wikipedian! [Besides, no adequate term exists in German either (would be Korrosivität); nonetheless it is being used every once in a while and everyone knows what it means because it is kind of self-explanatory.] -- 213.31.11.24 (talk) 17:39, 20 February 2008 (UTC)

It has been used in many books [1], so I think it is an acceptable word. As you say, it is more or less self-explanatory, and since it is kind of technical it's not on most dictionaries. Apparently it is listed on Merriam Webster Unabridged.[2] --Itub (talk) 18:08, 20 February 2008 (UTC)

New edit

The article has now been reordered so that metallic corrosion comes first rather than non-metal attack and degradation. The article still needs major attention to bring in case studies and examples of corrosive attack. Peterlewis (talk) 09:38, 9 May 2008 (UTC)

how the corrosion take place? —Preceding unsigned comment added by 119.82.89.129 (talk) 17:58, 9 May 2010 (UTC)

The article corrosion gives the answer :D --Chemicalinterest (talk) 00:10, 8 September 2010 (UTC)

Better websites for corrosion related articles!

Hello, I was going through the entire article on corrosion in Wikipedia for my research at school which is CASE western. All the information on that page seems to be really good. But I generally use the links that are at the bottom of article for farther research. But none of links provided have any comprehensive information in it. I use my school online library also for the research. We seems to be affiliated with a company called ASM International. They are some kind of research materials company. They have an professional website for corrosion called http://www.corrosionsolutionscenter.org/portal/site/csc/. They have some real good stuff in it. I was wondering if sharing of this website is possible. They have many other websites for various domains. But I think this one is useful.

Thanks, Regards, Mishaal Murawala mishaal12000@gmail.com

Thanks for the thought, but that website requires registration (and I think payment for registration), therefore, it isn't allowed per WP:ELNO. Wizard191 (talk) 21:00, 22 December 2010 (UTC)

Stress Corrosion Cracking

I think Stress Corrosion Cracking should feature more prominently in this article, probably as a new section. Does anyone agree, or should it be left as a separate failure mode altogether? Pelgrim 08:29, 3 August 2011 (UTC) — Preceding unsigned comment added by Errantchessman (talk • contribs)

Glaring lack of Citations in Lede

While most of the facts in the lede are relatively easy to confirm, it would improve the quality of the article if we were to add references for most of the facts being stated. --Ollyoxenfree (talk) 03:16, 11 May 2015 (UTC)

Electrochemistry

Where are the electrochemistry equations? 71.139.161.30 (talk) —Preceding undated comment added 20:13, 3 December 2016 (UTC)

Electron flow

What I'm missing is the clarification and definitions of 'cathodic' and 'anodic' current. Those names are vague although probably defined _somewhere_ and if one asks me quite out of date. I'd prefer more an explanation in the sense of electron flow and polarity of the current in cathodic protection. I'm not an expert in this field but, looking for a way to protect metal against corrosion, I can't from the article even figure out whether to apply a positive or a negative current to the metal to be protected. — Preceding unsigned comment added by Wikiario~enwiki (talk • contribs) 13:46, 2 October 2019 (UTC)

Merged content from old version of hydrogen grooving page

I have merged the content from the old hydrogen grooving page. i have corrected the hydrogen grooving page to point to Corrosion.

Lack of references

For an article that has been given a B rating, although there are plenty of inline cites, there are very few references. This needs quite a few more in my opinion. I mean High Temperature corrosion is woefully void. GRALISTAIR (talk) 22:55, 17 May 2021 (UTC)

Opening sentence defining corrosion

Oxidation of metals is too narrow a definition. It is any chemical deterioration of an object or structure, typically rendering it ineffective or less effective than its intended purpose. It could be by oxidation, dissolving, change of state, all sorts of things..... 2A04:C9C7:0:2412:34B9:4933:46FB:B9C1 (talk) 10:40, 20 October 2023 (UTC)

Can you point to documents supporting this proposed broad definition? In my experience both common and technical usage refer primarily to oxidation of metals. Musser (talk) 18:50, 10 November 2023 (UTC)
