What is the method for Physical Vapor Deposition?
editThis article has a short list of applications for Physical Vapor Deposition, but what is the actual method or process for PVD, for example I was curious about how it's used in depositing Indium-Tin Oxide on LCD screens, and what purpose the ITO serves afterwards, and how PVD is the only method suitable to deposit it for this purpose. -TAz69x 08:07, 26 June 2006 (UTC)
- I think it is a matter of cost. Sputtering is a very cost efficient way to deposit materials (I am not quite sure that is what they actually use, but one of the favourites of industry, because the process is very fast.) ITO is the standard material you use if you need to have material which shall be conduction and transparent. In an LCD screen you probably need electrical contacts from both sides, but the front contact should not absorb the light so you use ITO. I am not familiar with LCD technology, so I could be wrong about some details... --Do ut des (talk) 11:38, 17 December 2012 (UTC)
Copyright violation and fix
editThe article might have been NPOV, but some how it just read like some of the text came from a commercial document. I ran the phrase ""Cutting fluids cost companies today" and found three other sites with that sentence:
- pvd-coatings-for-cutting-tools.htm http://www.pvd-coatings.co.uk/pvd-coatings-for-cutting-tools.htm
- http://uk.geocities.com/pvd_coatings/home.html
- http://www.lycos.com/info/coating--products.html
I tagged the article as violating copyright. I went back through the edit histories to see how this got added. I found that in April 2006, Markj2006 added copyrighted material. I have cut and pasted together a new article using the edits before and after his insertions and placed it on the "temporary" page.--A. B. 23:05, 23 July 2006 (UTC)
Expert?
editHey wiki-folk, I have a Ph.D. thesis which includes lots of text and graphics that I could contribute to a number of pages, with some modifications. I use PVD equipment all day long (and have for years.) It might make sense to consolidate pages on vacuum evaporation, thin films, and Thin-film deposition or at least interlink them.
I have noticed that my IP address has been blacklisted as a vandal for reasons I don't understand. I believe my wife did try to do an edit once to remove obvious vandalism to a page (Tom Parker Bowles). Is there some way to make the system cool it and understand we aren't vandalizing? drjonfox —Preceding signed but undated comment was added at 00:33, 28 September 2007 (UTC)
- There are some definite organization issues between all of these various thin-film deposition articles. I'm still taking inventory of what is on Wikipedia, and I'm still rather new to this subject. However, I would propose we use the definitions provided by the Society of Vacuum Coaters, which are available as a PDF for download here.
- Concerning and issues with IP, it's a bit off-topic for this discussion, and considering the comment is over a year old, probably too late to help, but the general solution is to create an account on Wikipedia and do all editing while logged in. -Verdatum (talk) 16:36, 19 December 2008 (UTC)
Expert?
editPerhaps someone should try contacting Dr Peter Hatto, Director of Research for IonBond Limited. He is well known in the field of Coating Technologies - especially PVD technology. It is also interesting to note that there is no mention of IonBond in this section - they currently have a portfolio of not only PVD but also CVD and PACVD technologies. —Preceding unsigned comment added by 82.20.58.228 (talk) 19:35, 29 September 2007 (UTC)
Are the external links suitable? They seem to be just companies. —Preceding unsigned comment added by 89.242.10.37 (talk) 20:55, 7 October 2007 (UTC)
External link opinions
editOpinions would be appreciated on whether this link: PVD coatings theory Information about PVD theory and equipment would be an appropriate addition to the article. Thanks. -- SiobhanHansa 21:25, 8 October 2007 (UTC)
- No: Although the information appears solid, but (1) authorship is unknown (2) any references to reputable/verifiable sources of the provided information are absent. Therefore this website fails Wikipedia:verifiability criteria. `'Míkka 23:09, 8 October 2007 (UTC)
I will look up the references to the information provided and add it to the PVD coatings website so it meets the wikipedia criteria for verifiability.
I don't know the wikipedia criteria so I welcome other comments. By the way do we need to remove the other external links on the page as well? —Preceding unsigned comment added by 83.91.83.130 (talk) 13:40, 11 October 2007 (UTC)
I have added references to verifiable sources now. Is the [1] ok now? Thanks very much. —Preceding unsigned comment added by 78.145.168.41 (talk) 19:33, 12 October 2007 (UTC)
Improvement
editI think that we can definitely improve this page substantially to make it more useful than it currently is. It does not go into much at all, and is pretty much worthless. I think some repetition with the other pages is OK if this one expands to something that is useful.

This does not seem very likely to me - electroplated coats are very thin, the underlying metal substrate ( the article being electroplating ) usually is orders of magnitude heavier than the plated material. It is true that plastics are electroplated (using conductive coatings) but again I really have a tough time believing that any vehicle would weigh significantly less dependent on the metal coating technology used. Jon - visitor - not signed in - related experience, I have technical and practical experience in the field of electroplating. — Preceding unsigned comment added by 149.13.244.110 (talk) 17:48, 22 June 2015 (UTC)
Advantages & Disadvantages section
editI started editing the introduction block to remove repetition and neaten it up a bit. Whilst at it I decided to move the "Advantages" and "Disadvantages" section into one block which, for want of a better term I've called "Comparison..." but I appreciate that in its current state, the article isn't really "Comparing" PVD with anything, I wasn't sure that "Pros and Cons" was a particularly encyclopedic heading, any suggestions would be appreciated. I'm in the process of hunting for Review papers (preferably OA) that can back up some of the claims in this article. Matt-allinson (talk) 14:15, 9 October 2015 (UTC)
