corrosion products were cleaned with Clarke's solution IlOI. The corrosion inhibition efficiency (IE) was then calculated using the equation. IE= 100 [I -(W2/ W1)] % Where W, = Corrosion rate in the absence of inhibitor, W2 = Corrosion rate in the presence of inhibitor Surface examination study The carbon steel specimens were im Composition and corrosion behaviour of galvanised steel Apr 01, 2002 · The formation of conversion layers on galvanised steel from rare-earth nitrate solutions result in a surface film that constrains the cathodic reduction of oxygen and the anodic dissolution of zinc, leading to a decrease of the corrosion rate. The resistance to corrosion initiation under immersion in sodium chloride is dependent on the rare-earth cation:lanthanum seems to be more effective than
However, little research has been done on the corrosion behavior of carbon steel in the presence of both H 2 S and NaCl at ambient and elevated temperature. Corrosion mechanisms in oil field systems are complex and are showing high degrees of interaction between corrosion species, products, and oil field metallurgies. Corrosion Behavior of Mild Steel and SS 304L in Presence corrosion behavior of mild steel and SS 304L. The effect of Cu on corrosion rate of mild steel is quite pronounced and follows interesting trend. However, SS 304L is not affected either in distilled water or artificial seawater and do not show any significant variation in corrosion rates in presence of Cu ions.

The corrosion parameters of carbon steel immer-sed in river water in the absence and presence of inhibitor system are given in Table 2. When carbon steel is immersed in river water, the corrosion potential (Ecorr) is -463 mV vs SCE and the corrosion current is 1.556 x 10-5 A/cm2. When 50 ppm of Zn2+ and 50 ppm of calcium propionate are Corrosion behaviour of carbon steel in the presence of N Oct 01, 2001 · The inhibition efficiency of NcetylN,N,Ntrimethylammonium bromide (CTAB), a cationic surfactant, in controlling the corrosion of carbon steel in an aqueous solution containing 60ppm Cl, in the absence and presence of Zn2+ and also calcium gluconate (CG), had been evaluated by the weightloss method. Weightloss studies revealed that the behaviour of CTAB changed when its
The corrosion resistance of carbon steel after deposition of yttrium rich (hydr)oxide films on its surface was evaluated as a function of the Y(III) concentration in the solution, the immersion time and the presence of oxygen.
