Abstract

PURPOSE:To determine the velocity of deposition in nonelectrolytic plating reaction simply and quickly, by giving a fixed quantity of electric charge to a material to be plated instantaneously and measuring fluctuation of electric potential as the relation between polarization value and time. CONSTITUTION:An action electrode 11 consists of a material to be plated and a reference electrode 12 using as a standard for measuring electric potential fluctuation of the electrode 11 and also, an opposite electrode 13 using at the time of supplying an electric charge, are provided in a cell 14. A capacitor 15 is charged by a variable direct current power source 16 and the stored electric charge is given to the electrode 11 instantaneously by an electric charge giving mechanism 17. The electric potential fluctuation of the electrode 11 is measured as the relation between a polarization value eta and a time t and is sent to comparators 21 and 22 set at the different polarization values eta1 and eta2. These comparators 21 and 22 are connected with a clock 23 and the time difference at the time of each comparator has got polarization value, is measured.
