Unwanted Deposition in Brush Plating
2001
Hi!
I brush plate some components with hard chrome. The problem is that we sometimes observe some "deposit like" spots away from the area of work quite near to the area worked upon. Is it due to stray current being carried by the electrolyte? Will employment of a "sacrificial anode" attached at the peripheries of the stylus used solve the problem ?

A sacrificial anode will not work. What you need to do is mask the areas all around the desired plating area with platers tape or a peelable maskant. This will prevent any unwanted deposits.
