“…Benzamide can also be considered as an environmentally friendly inhibitor among many others that are currently receiving significant research attention in corrosion protection studies. [26][27][28][29][30][31][32][33] The results of the electrochemical tests obtained here are very much in agreement with the gravimetric tests. An appreciable effectiveness of the inhibitory properties of benzamide in the H 2 SO 4 test environments is achieved.…”

“…The two inhibitors used in combination, can also be considered as environmentally friendly inhibitors just like any others that are currently being used in corrosion protection research studies [27][28][29][30][31][32][33][34] . The combined trisaminomethane and hexadecyltrimethyl ammonium bromide was a good inhibitor for mild steel corrosion in the HNO 3 concentrations used.…”

The effect of combined trisaminomethane (THAM) and hexadecyltrimethyl ammonium bromide (HDTAB) as chemical inhibitors for corrosion of mild steel in 1 M HNO 3 was investigated at the ambient temperature of 25°C. The investigation was done with gravimetric (weight loss) method and also with the potentiodynamic polarisation technique. A potentiostat, Digi-Ivy potentiostat, connected to a computer for data collection and analysis was used for potentiodynamic polarisation experiment. The effective corrosion inhibition of the steel specimens in the HNO 3 test medium, using the combined inhibitors had its best performance achieved with the 6 g/ 250 mL HNO 3 concentration with weight loss of 2.99 g and a corrosion rate of 0.00913 mm/yr at 480 h of the experiment. This was closely followed with the 4 g/ 250 mL HNO 3 with 3.72 g weight loss at 480 h. At this concentration, the experiment also recorded polarisation resistance (Ω) values of 3.11E+01, corrosion rate of 1.95691E-05 mm/yr and current density of 0.000175A cm -2 for the 6 g 250 mL. The calculated inhibition efficiency values are, respectively, 39.2 and 24.3 % for both the 6 and 4 g 250 mL -1 HNO 3 concentrations at 480 h. The potentiodynamic polarisation results of ba and bc indicated mixed type inhibitors.

The effect of carbon percent on the corrosion of steel in ethanol -aqueous H 2 SO 4 solution has been studied by using weight loss technique. The effect of presence of foreign atoms in steel composition on the corrosion resistance has been investigated. Beside that, the effect of heat treatment on the corrosion rates has been interpreted. The inhibitive action of N, Ndihydroxy ethyl acryl-amide on the corrosion rate of steel appears high efficiency for all samples in all cases under study. The corrosion behavior is interpreted in view of the microstructure of samples before and after heat treatment. There are two wet corrosion processes that affected by carbon percent in the localized area. Before heat treatment the corrosion rate is more dependent upon inter-granular corrosion type while, increasing C % or by quenching regime the corrosion rate is more dependent upon allotropic-galvanic corrosion type. The corrosion rate in absence of inhibitors classified as cathodic control while it classified as cathodic-anodic control in presence of inhibitor.Key words: steel microstructure, corrosion of low and medium carbon steel, N, Ndihydroxy ethyl acryl-amide, heat treatment.
