摘要：
The influence of new inhibitor namely 1,3-bis-diethylamino-propan-2-ol (DEAP) on the dezincification corrosion of 65-35 brass in simulated atmospheric water was studied by potentiostatic current transient measurement, solution analysis and surface evaluation techniques. Potentiostatic current transient results showed that the investigated inhibitor can effectively inhibit the chemical dissolution of brass in simulated atmospheric water. Solution analysis revealed that the weigh loss of brass electrode remarkably decreased in the presence of DEAP, changing from 7.375?X?10-3?mg (blank) to 9.567?X?10-4?mg (10-2?M). The scanning electron microscope (SEM) and electron probe microanalyzer (EPMA) measurements showed that DEAP may better adsorb to zinc component than to copper component, inhibiting the dezincification of brass in solution by a mixed complex film of Zn(II)-DEAP and Cu(I)-DEAP. The nature of the inhibited film was analyzed by an X-ray photoelectron spectroscope (XPS) analyzer.
