Full TextAbstract
In the present work, a higher resolution than that of standard DL-EPR technique was obtained by tuning the degree of sensitisation (DOS) measuring parameters. SS304 with different sensitisation conditions was chosen. Acid and depassivator concentration, temperature, scan rate and reverse potential were defined as key factors and Taguchi L0 16 was applied. The optimal condition was found to be 1 M H2SO4, 0.02 M KSCN, 40 C, 30 mV/min scan rate and 200 mV reverse potential. Main factors were acid concentration, scan rate, depassivator concentration. An increase in DOS from 18 to 42.2 in the 60 min sensitised sample was observed.
