Study of surface morphology and inhibition efficiency of mild steel in simulated concrete pore solution by lactic acid–Zn2+ system

Abstract

The inhibition efficiency (IE) of lactic acid-Zn 2+ system in controlling corrosion of mild steel in simulated concrete pore solution (SCPS) prepared in well water in the absence and presence of Zn 2+ has been investigated by weight loss study. The formulation consisting of 250 ppm of lactic acid and 50 ppm of Zn 2+ provides 94% of inhibition efficiency. Inhibition was found to increase with an increasing concentration of lactic acid and Zn 2+ . Polarization resistance was measured by weight loss method, polarization study. The surface morphology has been investigated by SEM and AFM.

Electrochemical studies on the corrosion resistance of 18 K gold in artificial saliva, in the absence and presence of Gemer-2 tablet (orally taken by type 2 diabetes)

“…Electrochemical studies are used to measure the corrosion resistance of metals and alloys in various media. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] The corrosion resistance of 18K gold in aritificial saliva, in the absenc and presence of Gemer-2 has been evaluated by electrochemical studies such as polarization study and AC impedance spectra.…”

Influence of some tablets on corrosion resistance of orthodontic wire made of SS 316L alloy in artificial saliva

“…The AC impedance spectra of SS 316L alloy immersed in Artificial Saliva (AS) in the absence and presence of five tablets obtained from AC impedance spectra are shown in Figures 4, 5. The AC impedance parameters namely charge transfer resistance (R t ) and double layer capacitance (C dl ) derived from Nyquist plots ( Figure 4) and Bode plots ( Figure 5) are also given in this Table 3 [17][18][19][20][21]. In the Nyquist plot the extreme point in the high frequency region corresponds to R s (solution resistance).…”

Synthesis of a Non-toxic Organic Ionic Liquid Triazole Derivative: Application in Inhibition against Corrosion Copper in a Neutral Chloride Environment

“…1 This is one of the major challenges in industrial processes, resulting in considerable financial losses. 2,3 For example, exposure of copper and its alloys to seawater deteriorates their structure and promotes accelerated corrosion of metals. In addition to property damage, copper corrosion can lead to environmental problems due to the release of harmful products (corrosion products) into the environment.…”
