The corrosion inhibition efficiency offered by 50 ppm of Ni-HUF is 74 %. The corrosion inhibition was observed due to the formation of more stable and compact protective film on the metal surface. Fluorescence spectral analysis was used to detect the presence of iron-inhibitor complex. Polarization study and Electrochemical Impedance spectra confirm the formation of a protective film formed on the metal surface.

The results show that 65% inhibition efficiency is achieved with binary system consisting of 250 ppm of DTPMP and 50 ppm of Al 3+. Polarization curves indicate that the system is a mixed inhibitor. The surface morphology of the metal surface is examined using the scanning electron microscope.

A potentiodynamic polarization study and AC impedance spectra have been used to investigate the corrosion behavior of these metals. The corrosion resistance of these materials in artificial saliva, in the absence as well as in the presence of D-Glucose, increased in the following order: SS 316L > MS-Zn > MS.

The formation of polymer-salt complex has been confirmed by FTIR spectral studies. The temperature dependence of conductivity of polymer films seems to obey the VTF relation. Values of conductivities of the polymer complexes are presented and discussed.

Mild steel in concrete structures may experience corrosion. To avert corrosion of mild steel, a number of inhibitors are used along with concrete admixtures. In this category of research, saturated calcium hydroxide solution is considered as simulated concrete pore solution (SCPS). Numerous corrosion inhibitors have been utilized in this field along with organic coatings. In the present investigation show case polish coated mild steel has been used in concrete. The corrosion resistance has been calculated by electrochemical studies such as polarization study and AC impedance spectra. When show case polish coated mild steel is immersed in SCPS, the corrosion resistance of mild steel increases. This is long-established by the facts that in presence of show case polish coating , the linear polarization resistance value increases, corrosion current value decreases, charge transfer resistance incr...
