SIMULTANEOUS THICKNESS AND ELECTROCHEMICAL POTENTIAL DETERMINATION OF INDIVIDUAL LAYERS IN MULTILAYER NICKEL DEPOSITS USING THE CHRYSLER "STEP" TEST
The Chrysler "STEP" Test is used to simultaneously measure the thickness of the individual nickel layers in multilayer nickel deposits as well as the electrochemical potential difference between the nickel layers. This newly developed rapid test obviates the need for microscopic thickness measurements in many cases. More importantly, the electrochemical potential difference between nickel layers can be very easily measured. Development of the test, typical results obtained on good as well as unsatisfactory deposits and implications with respect to improving corrosion resistance of plated parts are presented.
