Abstract
the gap. These experiments are conducted on the crevice formed by SS400 Steel and the C27000 Brass based on gap-distance parameters in the polluted ammonia environment. Such crevice often found in boiler joints, turbines, and machinery parts. The corrosion rate of SS400 steel when it stands alone in the ammonia environment is 0.7554 mpy, while the interface potential is -130 mV VS Cu/CuSO4. The corrosion rate of C27000 Brass when standing alone at related ammonia environment is 20.144 mpy, and the interface potential is -1191 mV VS Cu/CuSO4. When both metals combine to form a crevice, the corrosion rate of steel increased by 28% averagely. The tests include a gap where the two metals were mating each other (no distance), forming a distance of 0.239 mm and 0.398 mm. The interface potential of both metals when touching -518 mV VS Cu/CuSO4, -288 mV when formed a gap distance 0.239 mm and 0.398 mm. On the contrary, the corrosion rate of Brass C27000 decreases significantly up to 60% when joining to create a gap with steel. The interface potential of Brass C27000 when forming a gap with no distance with steel is – 632 mV VS Cu/CuSO4.
