I need to passivation on the nickel film to create a polymer structure, but in acid this is not possible, the film goes away instantly. How can passivation be achieved other than acid?
Nickel film passivation can be done without acid using a process called "thermal oxidation". This process involves heating the nickel film in air or oxygen atmosphere to form a thin oxide layer on the surface, which can protect the underlying nickel from further oxidation and corrosion.
The steps involved in thermal oxidation for nickel film passivation are as follows:
This process can be performed in an oven or a furnace that is equipped with precise temperature control and gas flow management. The thickness and properties of the passivation layer can be controlled by adjusting the temperature, duration, and oxygen flow rate during the process.
Thermal oxidation is a relatively simple and low-cost method for nickel film passivation compared to acid-based methods, which often require specialized equipment and handling procedures to avoid safety hazards and environmental concerns.
Thank you for your detailed answer. Is there an article on how we should determine the film thickness, 25 nm meters, temperature and time? I would be happy if you share. Febin Cherian John
I don't think these might be of your requirements, but kindly have a look.
Hope this helps. Thank you
Unfortunately, I could not find these publications with the title and author name you wrote. "Passivation of Nickel Thin Films on Silicon Substrates" by T.S. Sudarshan, et al. unfortunately it didn't come out when I wrote it like this. thanks..
