EXPERIMENTAL APPLICATION OF DESIGN PRINCIPLES IN CORROSION RESEARCH.

Experimental design criteria for corrosion investigations are based on established principles for systems that have uniform, or nearly uniform, corrosive attack. Analysis reveals how experimental parameters influence behavior, and in particular how the use of dimensionless groups help to evaluate the competing influences of different parameters. This measure of the relative importance of interfacial kinetics, solution conductivity, and mass transfer, provides a basis for designing laboratory experiments for materials testing and selection, and for scaling laboratory measurements to service conditions. Some applications to materials protection are briefly discussed.
