Electrode potentials in AL-Zubare harbor water (South -Gas Company). of 23. 88 ohm-cm at 20oC were reported for 26 metals and alloys includingvalues for electroless nickels that signify a greater passivity than steel. Thelarge potential difference between steel and electroless nickel predicts severegalvanic corrosion. https://www.lisamalloryphoto.com/product-category/sleep-apnea-aids/
