Abstract
We investigated the effect
of microbubble dispersion in a Watts-type Ni bath containing phosphorous acid
on the chemical composition and crystal structure of Ni-P alloy electrodeposition. The presence of microbubbles during electrodeposition
was found to accelerate the co-deposition of phosphorus into deposits,
resulting in the amorphization of the Ni-P deposit.
Key words : Microbubble, Electrodeposition, Ni-P
Alloy, Amorphous
