Talk:Electroless deposition

The equation given in the text must be wrong, it is not chemically balanced. I.e. it does not have the same number of each atom on the left and right side. GibsonDavidBCRA (talk) 14:17, 1 January 2019 (UTC)

Evaluation of the the Wikipedia article
Summarize the current status of the article in terms of content, tone, and citations.

Content

https://en.wikipedia.org/wiki/Electroless_plating

The Wikipedia page, I have chosen to edit for my project is electroless deposition (link embedded above). Within the 1st paragraph a embedded link can be included to the a page on autocatalytic Wikipedia page. The article contains 4 sections (history, general process, man processes, and references) but needs improvement on through the addition of subsections including such as the discovery, improvement on the process, and transparency on multiple metal deposition developed throughout the last 2 decades. The historical section of the articles lacks information on the 5 developmental stages of electroless deposition: discovery, a period of slow growth, a period of rapid development, and a period of deeper development. Although, Wurtz’s discovery of the process in 1848 has been mentioned and patent in 1914. It could be improved by mentioning the explosion of the number of U.S. patents throughout the 20th century into the 21st century. Currently electroless deposition is one of the main methods used for making non-conductive surfaces conductive but there are other methods such as vacuum thermal evaporation, electroplating, and electron beam evaporation that are not mentioned as a comparison for making a case for the advantages of electroless deposition. Another section could be included for the big industry players within the electroless deposition for the last few decades including understanding environmental impacts and waste management plans (OSHA requirements). The general stages for electroless including pretreatment, sensitization, activation, and deposition are missing. Although the process is viewed as simple it is complicated there are also required binding agents, and pH balance etc.

The article has a neutral tone overall but overall, the main electroless deposition of nickel alloys are favored over deposition of other transition metals. The redox equation provided needs to be corrected because it is missing charges for the reducing agents. The equation could be improved by also including the typical exams of the most used reducing agents with a schematic of the exchange of electrons for final products after the reduction of the metals. On the talk page a reviewer has pointed out this error, but the article has not been edited to reflect this change sing 2019. Also, missing are schematics of the metals passing through a diffusion layer to get to the surface of the substrate along with examples of the how the metals are layered on the substrates. Of the 13 citations of 6 (citations 8-13) are written by a man, Abner Brenner, which creates a bias towards his opinions. In fact, most of the articles are also written by men with a bias for older citations from 1882-1950 which does not include many secondary sources such as more recent books and possible scientific thesis written in the 21st century. With an obvious bias to Abner Brenner et al., which is not noted within the article there are also links to German and French articles which I am currently searching for English translation. The references are appropriate and reliable on the page and are easily found by a google scholar search. I plan to expand this by adding between 20-25 articles. All hyperlinks within article provides guidance to the correct Wikipedia articles. I have included some of the integral changes that I will be making in the previous paragraphs, I think the following sections need to be included as well including links to the methods that be used to evaluate the morphology, growth of the nanoparticles, and the nucleation sites. The techniques that I will be including are characterization are SEM-EDS, ATR-IR, TEM, EDX, EPS, and pXRD.

Renaming the article
This article is currently referred to as 'electroless plating.' This article also provides other names such as autocatalytic plating or chemical plating for this process. There is a process known as electroplating which uses electric current input. Since electroless plating advantages include removing energy inputs. Electropleting also has an industrial connotation an industrial process. This article focuses on the chemical process of electroless plating and not on the industrial application. The processes mentioned above are very different but their names could cause confusion with the use of the word 'plating.' Another name being uses by primary and secondary sources, and companies is ' electroless deposition.'

Changing the name of the article to 'electroless deposition' and provides an opportunity to remove any confusion readers might perceive with electrolplating and electroless plating. JamaicaWilliams (talk) 22:00, 12 February 2023 (UTC)
