Sulfide Solution

The oxidation of sulfide was investigated at a potential of about -0.1 V, 60 °C and electrolyzation time of 48 h, the sulfide ions were oxidized to sulfur and polysulfide, and the predominant polysulphide was S22-. The behavior of the anodic oxidation was highly dependant on the applied temperature and the concentration of the sulfide ions.

The influence of small variations in the composition on the corrosion behavior of Co-Cr-Mo alloys has been studied using scanning electron microscopy (SEM), energy dispersive x-ray analysis (EDX), and electrochemical measurements. SEM and EDX data were correlated with data from in vitro corrosion measurements involving repassivation and also potentiostatic anodic polarization measurements. Specimens studied included the four alloys shown in Table 1. Corrosion tests were conducted in Hanks' physiological saline solution which has a pH of 7.4 and was held at a temperature of 37°C. Specimens were mechanically polished to a surface finish with 0.05 µm A1203, then exposed to the solution and anodically polarized at a rate of 0.006 v/min. All voltages were measured vs. the saturated calomel electrode (s.c.e.).. Specimens had breakdown potentials near 0.47V vs. s.c.e.
