[edit] Jargon

 This article may be too technical for most readers to understand, and needs attention from an expert on its subject. Please expand it to make it accessible to non-experts, without removing the technical details.

This article makes use of all sorts of metalurgy jargon which the reader is clearly expected to know. Perhaps some of it can't be avoided. In that case, said terms should be wikilinked.

I'm tempted to go in and wikilink them myself, but that's a slippery slope. It'd be better if someone who knows their stuff were to go through and decide what terms should be briefly defined in the article, and what terms should simply be linked to their respective articles.

[edit] Repetetive Redundancies

''''''I notice that an edit added "The pipes can accept certain dyes which provide a coloured finish." Given this is covered in the last para does this information add anything? It is repetition, but which should go and which stay? Ian 15:17, 26 Jul 2004 (UTC)

Doesn't greatly matter. I realised my mistake shortly after making it, byt had a loss of connectivity before I could get back to fix it. I have reverted my changes out. Rich Farmbrough 22:02, 27 Jul 2004 (UTC)

Chronologically, your place for the info. was better. But as it's less important than the actual process, having it separate seems OK. As you say, it doesn't matter than much. Ian''''''

[edit] What carabinders?

I can't get the caribiners picture to show up on the article. --Auric 04:48, 13 January 2006 (UTC)

I think there's a temporary server problem. —BenFrantzDale 04:58, 13 January 2006 (UTC)

[edit] Anodised Titanium

This seems to be quite Aluminium-centric. What about Titanium? [1] -- Sy / (talk) 20:52, 11 May 2006 (UTC)

[edit] Anode (negative electrode?)

The article states that the aluminium is made the anode (negative electrode). I was under the impression that an anode was the positive electrode and the cathode the negative electrode. I think the aluminium is made the positive electrode (anode) as aluminium ions are Al2+ (?) so needs to be the anode. This is in order to be oxidised by the oxygen ions.

[edit] The anode is positive

I have just read the comment on the discussion page that points out that the anode is positive and the cathode is negative. This is correct. I don't know how to amend the article, but it should be amended to ensure that it is correct.

[edit] cold sealing

"Sealing at 20 °C in nickel-cobalt salts, cold sealing, when the pores are closed by impregnation is also popular due to energy savings. Coatings sealed in this method are not suitable for adhesive bonding."

Is cold sealing the name for any process with nickel-cobalt salts at 20 degrees? Should we say room temperature? Can I assume it can be just around 20 degrees? Maybe it's only called cold sealing when "the pores are closed by impregnation" and other times it's just nickel sealing? --Gbleem 02:29, 25 December 2006 (UTC)

"Anodization changes the microscopic texture of the surface and can change the crystal structure of the metal near the surface." Should I say can or does? Does it always change the structure of the metal layer? --Gbleem 02:54, 25 December 2006 (UTC)

[edit] Request for anodisation specialist review

Sorry for the off-topic post, but I have a hypothesis about anodizing aluminum with DNA that I've written up (perhaps not so clearly) at http://infoeng.sf.net/dic-proposal.pdf . I would be enormously grateful if anyone could provide me with any feedback regarding that paper. Thanks. :) JPatrickBedell 22:53, 11 February 2007 (UTC)

[edit] British vs. American Spelling

Not a big deal from a science standpoint of course, but jumping back and forth in spelling variants isn't ideal. Pick one or the other. The vast majority of references in the article and on the web are of the American spelling so I changed the rest in the article (may have missed a few) to match. I cannot figure out how to change the title of the article though. —The preceding unsigned comment was added by 128.120.179.12 (talk) 00:13, 24 February 2007 (UTC).

Note that you shouldn't have done this- pages are meant to stay at their original spelling. 124.171.130.134 (talk) 07:13, 12 June 2008 (UTC)

[edit] Chemically bonded to surface

I removed a few statements which said the strength and adhesion of anodic films could be explained by the fact they are chemically bonded to the surface, or that they are grown on the surface. Paints, chromate conversion coatings, and arguably platings are also chemically bonded, but they crack and peel much more easily than anodic films. The reason for the greater strength of anodic films has to do with the fact that oxygen binds to metals better than anything else, and that most metal oxides like alumina are very strong by themselves, which is again due to the strong oxygen bonds. But I don't have a clean way to explain that, nor do I have references to cite.--Yannick 02:38, 20 May 2007 (UTC)


[edit] Hot Sealing process

I'm curious as to whether the hot sealing process (normally immersing in boiling water) is a chemical or thermal reaction/process - can anyone clarify for me? It is unclear from the main page.

Note that the dichromate seals are also hot processes. But I don't know the answer to your question.--Yannick 17:17, 6 October 2007 (UTC)

[edit] Process Specification Details

It looks like someone included too many or not enough zeros on some of the thickness specifications for MIL-A-8625. —Preceding unsigned comment added by 216.182.41.210 (talk) 13:29, 9 June 2008 (UTC)
