In my literature studies, I saw that aluminum alloys are coated with Nickel-Boron. What I want is for it to be covered only with boron without the use of nickel. Is it possible to coat aluminum alloys with only boron-containing substances without substances such as nickel and tin?
In Ni-P-B coatings, boron is included as an optional additive. The basis of this coating is nickel-phosphorus and the composition of this base is due to the method of coating, - deposition from solution. All Ni-P-based coatings, known as electroless nickel, are produced by chemical deposition and therefore cannot be altered. At the same time, there are many different additives to the solution for deposition of Ni-P coating that can improve the wear resistance of the final coating.
In other words, it is possible by chemical deposition to obtain a Ni-P-B coating on aluminum, but not possible a pure boron coating.
Boron coating on aluminum or other substrates will require other methods such as vapor deposition (PVD).

this can be helpful dear
One possibility is that 2D-Borophene (allotrope of boron) is a strongest materials which can freely grow on Aluminium substrate by sputtering and annealing in ultrahigh vacuum condition
Dear Vadim Verlotski , Dear Muhammad Saqlain Qurashi , Dear Frank Kern and Dear Loganathan Kulandaivel Thank you very much for your return. What I want to do in my study is to coat Aluminum parts with Boron-containing substances (sodium borhydride, dimethyl amino borane, hexagonal boron nitride, titanium diboride) using Sol-gel, current (electrophoretic) and non-current methods without using any by-products. When I review the answers from you, I understand that this process will not be with the methods I have determined. So, how can I make a coating using the methods I have determined (Sol-gel, current (electrophoretic) and non-current method). Are there any suitable bathroom components that you know of for these?
Dear İsmail Gündüz this is a very interesting technical question. First of all, please note that the compounds you mentioned are very different in nature. Sodium borohydride and dimethylaminobprane are either salt-like or molecular compounds which are not really suitable for coating metallic substrates. In contrast, coating of aluminum and aluminum alloys with boron nitride is possible and well-established. In this context, please have a look at the following relevant literature reference which might help you in your analysis:

Dear Frank T. Edelmann, first of all, I would like to thank you very much for making a return. I have reviewed the article you have submitted. I saw that boron nitride was used in the study. I am also looking into what other components other than boron nitride can be made with in my study. in the literature studies I have done, I have seen that sodium borhydride is used more in the sound. at the same time, I would like to make coatings on aluminum 7075, 6061 and 5754 alloys using solgel, electrophoretic and electroless methods in my work. Which boron components should I prefer in the bathroom components in this regard?
Dear İsmail Gündüz many thanks for your kind response and explanation. Clearly sodium borohydride itself is unsuitable for coating metals or metal alloys with boron species. NaBH4 is a water-soluble salt which has highly reducing properties. However, sodium borohydride is often used as a reducing agent to prepare metal coatings and metal nanoparticles.
In your case I assume that for coating aluminum and aluminum alloys with boron compounds you should look for hard and resistive materials like metal borides and boron carbide etc. For some potentially useful articles about this topic please have a look at the following papers:

One of the authors of the first article is an RG member. Thus you can easily contact him directly via RR at https://www.researchgate.net/profile/Fabienne-Delaunois and request the full text of the article from him.
Good luck with your research and best wishes, Frank Edelmann
Dear Frank T. Edelmann . I really appreciate you passing on your information. I will review the articles you have submitted.
