Summary for electroless coatings research Discussion
Electroless coatings research is the main focus of this thread, with Shweta asking for a PhD-suitable project in electroless coating or pulse plating. Sridhar Bushigampala says electroless nickel is the most widely used engineering deposit, followed by electroless copper for circuit boards, and notes that RoHS-driven efforts are pushing the industry away from hazardous additives such as lead and cadmium toward alternatives like bismuth and even non-metallic additives. James Watts adds that the best topic depends heavily on the major professor’s interests and the student’s background. He warns that electroless nickel involves many variables and disposal issues, while pulse plating may require higher startup cost but could be easier and cheaper to publish because the key unknown is finding the best operating window for a given plating solution.
Q. Sir
I am a physics and materials science background person, I want to do research work on electroless coatings, or pulse plating. So please suggest me a good work which should be helpful for my Phd also.
with regards,

A. Hi Shweta,
In electroless coatings , Electroless Nickel deposits are widely used for engineering applications then comes electroless copper mostly for circuit boards.
Recently European Union is trying to eliminate hazardous substances (RoHS) from Electroless Nickel Coatings.
Main additives of electroless nickel are Lead and cadmium as stabilizer and brightener
New technologies are coming up with alternatives such as bismuth etc.,
Some even are trying to work with non metallic additives.
I hope it helps.

A. That will be greatly dependent on the background and desires of your major professor.
For EN, you will go thru dozens or hundreds of variables and have a disposal problem.
Pulse, costs a lot more for the startup, but the big unknown is the best “window” for a given plating solution and would probably be easier and cheaper to publish your dissertation.
