Isoniazid (anti-biotic) derivatives—PA1 {(E)-N′-(4′-Hydroxy-3-methoxybenzylidene) isonicotino hydrazide}, PA2 {(E)-N′-(Pyridin-4′-ylmethylene) isonicotino hydrazide}, and PA3 {(E)-N′-(Pyridin-3′-ylmethylene) isonicotino hydrazide} were synthesized, characterized, and further examined for corrosion protection activities on mild steel (MS) in 1 M HCl via experimental, theoretical, and surface analysis...
The comprehensive investigation results of the microstructure, mechanical properties and corrosion resistance of the Al2O3 thin films deposited on hot work tool steel substrate are presented in the paper. Aluminium oxide layers were prepared using atomic layer deposition (ALD) method in temperature 150, 225 and 300 °C.The uniform structure of the investigated coatings without any visible delamination...
The passive behaviour in artificial sea-water of Cr-implanted (4x10 16 ions/cm 2 , 60 keV) and non-implanted Ni was studied at room temperature by electrochemical impedance spectroscopy (EIS) and X-ray photoelectron spectroscopy (XPS). The transfer resistance obtained for the implanted specimen (R t ~5586kΩcm 2 ) is extremely enhanced compared to the corresponding...
