Fig. 2 shows the variation of the open circuit potential (OCP) of 316L steel alloy monitored during the first 70. h of immersion in the carbonate mixtures.. It can be seen that after several hours the OCP appears appreciably shifted toward more noble values by the addition of Mg and Ca cations, whereas only a marginal shift is observed …
To study the scale inhibition of calcium carbonate by cathodic and anodic processes, the electrodeposition of calcium carbonate was performed by Edvardsen and colleagues. They reported the growth of calcium carbonate deposits on graphite cathode and anode, at different calcium chloride concentrations (0.5 and 1.5 wt% CaCl2) and positive potentials

Chromium increases the corrosion resistance of steel, and a minimum of 12% chromium is necessary to produce a stainless steel. The best known of the stainless steels contains about 74% iron, 18% chromium and 8% nickel (known as 18-8 stainless). Stainless steel is perhaps most familiar as kitchenware (sinks, kettles and cutlery).
