You can ignore all I say after this next paragraph or you can read on.
Based on my failing memory, Internet searching and some reading, I have the feeling that you can get results you are looking for with less than 12 volts (maybe less than 6 volts). From what I understand if you go too high in voltage you will get side results that may adversely effect you desired outcome.
Now for my discussion --
What's up with you,man?
We are all volunteers here, so I only been on here briefly during the weekend to make sure that my moderation duties would be taken care of properly. Therefore the time to do the research necessary to answer your question was on hold.
Even then I am not sure I can give you a definitive answer. Based on the below links you will notice that there are a number of factors that effect your process. For instance the distance between wire (on one side) and the object (on other side) you have in the process could influence what you might use in voltage. From what I could glean from from my research so far is that the amperage may be a more important measurement. http://www.ami.ac.uk/courses/topics/0223_plate/index.htmlhttp://chem1.eng.wayne.edu/~yhuang/Papers/Book_Plating_ECHP.pdfhttps://www.glastonburyus.org/staff/BREINANH/APChem/APlabs/Documents/electroplating.ap.student.dochttp://www.youtube.com/watch?v=YvYCc8F-8rQhttp://www.youtube.com/watch?v=Q8Xo43sfLgY
I was going to read more to see if I could resurrect my memory of electroplating, but decided to pause here for now.
For your part --
I had asked for more detailed information from you and I get answers from you that are too general.
I am looking for more precise answers from you for 3 reasons.
One, it is possible that someone on this forum who does or teaches electrochemistry may become more involved with participating in the discussion. I do have to admit that if there are members with this expertise, they are not always regulars.
Second, I was thinking of putting together your setup and testing for myself, so as to add to the discussion.
That is why I asked for
A link on the Internet that you might be using as a guide, since you said you looked around.
Yet you provided no link that is close to what you are doing.
The exact recipe' of ingredients you are using in the process.
Yet your answers were general.
The equipment you are using for the process.
Yet I still do not know the make and model of your power supply.
Now if the process you are working on is proprietary, you can contact me off line and I will understand.
Thirdly, IF YOU HAD READ THE FORUM RULES
We are not supposed to just dump an answer on you.
Instead we are supposed to teach you how to get the answer yourself.
So asking questions in a Socratic method is the desired approach.
In this case both you and I would have learned.
By the way, there was an entry that suggested that your process might not need the electric part, but might take longer to see the results. But, we did not take the hint.
As far as the Internet --
I can see where it is difficult to get what you want on this topic.
When I did a search using GOOGLE, using different criteria, I got results that were too general, too conflicting, erroneous or to difficult to access. It took me several tries and many pages to get the few I have above. And, I still am not sure they are entirely accurate.
As a side note --
What we are discussing here, will potentially help me. Currently I am casting sculpture in brass and aluminum. It is possible that i might want to finish some of these sculptures using electrochemistry. For my part, I will be looking for a power supply where I can both measure and control the voltage and amperage.
I would like to end this thread
You can not end this thread.
It will live on.
And, hopefully will have additions that will make it useful to the next reader.
Additionally, it may attract another member to participate
who is more experienced
who is more current in the technology
who is more academically involved in electrochemistry.
I hope you will stick around and see where things go.
If I do any of this, I will be sure to post here.
I still have to tool up my laboratory and memory.
In the mean time I am going to probably post something about your ingredients when I have time.
