METHOD FOR DETERMINING ALLOY PHASE IN PLATING LAYER AND METHOD FOR EVALUATING SLIDING PROPERTY OF ALLOY GALVANIZED STEEL PLATE

摘要

A method for determining a quantity of each of alloy phases in the plating layer includes subjecting each alloy phase in the plating layer to constant potential electrolysis in each of a plurality of ranges of potentials obtained on the basis of the immersion potential of each alloy phase and the immersion potential of a basis metal, by using a plated metal material having different kinds of alloy phases in the plating layer as the anode, to determine the quantity of each alloy phase in the plating layer on the basis of the quantity of electricity consumed in each range of the potentials during the electrolysis. <IMAGE>
