Talk:Wear

message: This article does not address material loss and deformation through direct angular impingement of a solid under velocity on to a surface. I believe this would or should be classified as balistic wear?
:It is actually termed as erosion by solid particle impingement (see ASTM G76 for more details). Some people (even ASTM) call it erosive wear. The maximum material loss is observed around 20 degrees. There are many forms of erosion like abrasive erosion and cavitation erosion. Drajput (talk) 13:55, 14 October 2009 (UTC)

message: Wouldn't fretting wear be considered a wear as well?  Fretting doesn't fall into any of the current four catagories of wear though it can be a precursor to Abrasive wear. Lukeseed (talk) 20:03, 19 November 2007 (UTC)
replies: text: I agree - I would also take out "surface fatigue" and instead have "fretting fatigue". Surface fatigue does not generally involve wear. I can do the necessary edits once I find a valid source. Sigmund (talk) 21:35, 21 November 2007 (UTC)

message: I have reverted a change to the number of wear modes by an anonomous user for the second time, but did not check to see if it was the same IP/subnet -- Am I missing something here? The change was the same, is there a good reason for the change that I don't see? User A1 (talk) 00:26, 21 October 2008 (UTC)
thread_title:  Number of wear modes 

message: The definition of wear is not appropriate in the opening statement. The word "erosion" should not be there as erosion by itself is a kind of wear. It will be better to use the definition by ASTM. Drajput (talk) 21:43, 13 October 2009 (UTC)
replies: text: The definition of wear may include loss of dimension from plastic deformation if it is originated at the interface between two sliding surfaces.However, plastic deformation such as yield stress is excluded from the wear definition if it doesn't incorporate a relative sliding motion and contact against another surface despite the possibility for material removal, because it then lacks the relative sliding action of another surface.Impact wear is in reality a short sliding motion where two solid bodies interact at an exceptional short time interval. Previously due to the fast execution, the contact found in impact wear was referred to as an impulse contact by the nomenclature. Impulse can be described as a mathematical model of a synthesised average on the energy transport between two travelling solids in opposite converging contact. Cavitation wear is a form of wear where the erosive medium or counter-body is a fluid.Corrosion may be included in wear phenomenons, but the damage is amplified and performed by chemical reactions rather than mechanical action.

thread_title:  Definition of wear 

message: I want to correct the section about adhesive wear and material transfer.
My investigation but also other investigations, refereed to in the text, clearly state that material between the two interfaces exhibits a clear change in plastic behaviour. 
Such a change in material behaviour is not possible without high pressure and/or temperature in the demarcated, deformed, volume. 
It is clear that a high energy content, pressure or temperature can be very local, especially around sharp tools or penetrating objects, because energy or heat transfer away from the contact zone is highly dependent on the surface area of the deformed volume.
For example, water doesn't evaporate in vacuum if it´s injected whit high pressure and have a small surface area, because the energy content, pressure is high and the surface area doesn't´t allow instant and total loss of energy and immediate water evaporation. 
I wan´t to correct the section whit regards to the above explanation, thank you.

thread_title:  Adhesive wear or material transfer from one surface to another demand a raise in energy content, pressure or temperature 

message: I would like to discuss citation 8 in the wear article presently found in the Wikipedia archive, the citation reads quote,"Surfaces also generally have low energy states due to reacted and absorbed species." end quotation, the sentence is strange because debris in frictional contact can be of hardened phases and other high energy formations.It isn't certain that adhesive wear is exothermic in nature and free stored energy. 
The accumulated high energy found in debris and remainders found in the tracks after sliding contact and adhesive wear is the product of plastic deformation and plastic flow.
I would like to politely remove or rewrite the sentence or at least ask someone why it´s present and perhaps the details might it justified. It seems a bit confusing with regards to the other parts in the text.
Also the reference is rather old and perhaps doesn't comply to knew findings in the latest research in adhesive wear.

thread_title:  Adhesive wear usually involve plastic deformation

message: Unless this stub of an article is going to grow extensively soon, I don't see why it deserves its own article. It can easily fit into this article, even if it does grow moderately. Wizard191 (talk) 22:08, 17 May 2011 (UTC)

message: I feel the section on friccohesity is not well integrated with the rest of the article. Also, its length would justify a standalone article. If there are no strong objections, I'll move the contents to a separate page soon.Moritz Ploss (talk) 20:50, 7 March 2018 (UTC)
