Efficiency of Ni-P alloy plating


Has anybody experiences in electroplating a Ni-P alloy (not electroless but electroplating) concerning efficiency.

You'll have to do a literature search that goes back a few years, but there are published articles about nickel-phosphorous electroplating. As for the efficiency, well, if there's any hypophosphite in it, it's probably greater than 100 percent.

It depends on the phosphorous content in the deposit. If you are looking for 10-15% by weight P the efficiency is between 50-65%.
