Question about reverse plating in Watt's bath

do the pulse reverse plating affect the titanium baskets on a watts nickel bath? for example it does not activate the titanium allowing it to get dissolved in the bath?

Hi, Daniel. In applications where reverse polarity is commonplace and efficiency is low, like certain Wood's nickel strike ⇦ huh? sequences, cast nickel anodes are used rather than anodes baskets. I have not used pulse plating in a Watts' nickel bath, but I am not understanding why the baskets being cathodic would activate them, especially at moderate voltage, reasonable efficiency, and low duty cycle. But, as I say, that's a guess.

Are your baskets actually dissolving? I'd be amazed if they were. If they are, I can't imagine how pulse-reverse rectification could be the culprit.
