Does anyone know (or have references) on how to deposit tin onto a core of copper and silver alloy particles? The deposition should be, at best, a shell of tin but could also be an "attachment" onto the particles.
I was thinking about electroless deposition with a reducent (NaBH4?) in aqueous solution.
Do anyone have experience with this?
Dear researcher as far as my concern plasma spray process may help you regarding homogenous defect free coating.
I think I would try the electroless approach, however you may have to be careful of the bath / solution "bombing out". I've not tried electroless tin, but platinum has been satisfactorily deposited with NaBH4.
Thank you Gavin, what do you mean for "bombing out"? It sounds kinda scary... I've never used NaBH4 as reducing agent so let me ask you, can you suggest an initial concentration of salt to start with? Do you recommend to add some surfactant as PVP to improve the quality of deposition? PVP does a great job against dendrites in flat sheet deposition but I don't known if it will do it on particles. Thank you
I'm researching on the tin coating on brass substrate by electroless process.
My main question in this research to find a solution composition used in the process.
can you help me?
