Corrosion inhibition of aluminum by coatings formulated with Al–Zn–vanadate hydrotalcite

Microstructure and Corrosion Performance of Silica Coatings on Aluminum Surface Prepared by Plasma Electrolysis Technique

Silica phases were precipitated on aluminum surface by potentiostatic plasma electrolysis technique. Aqueous sodium silicate solutions with different concentrations were used for this purpose. SEM, EDS, XRD, surface profiles and polarization curves were used to study coatings properties. The results showed that the growth of the silica containing phases on aluminum surface was promoted by incre...

Corrosion-Resistant, Chromate-Free Talc Coatings for Aluminum

Aluminum (Al) and Al alloys exhibit unusual passivity when immersed in alkaline lithium (Li) salt solutions. This passivity is a result of precipitation of a continuous, polycrystalline talc coating. Talc coatings persist when removed from the Li salt solution and offer increased corrosion protection during exposure to aggressive environments. Efforts to develop a low-cost, low-toxicity, easily...

Inhibition of Copper Corrosion by Ethanolamine in 100 ppm NaCl

We study copper corrosion inhibition by ethanolamine (ETA)with (0, 0.2 ,0.3,0.4,0.5) vol.% concentrations in 100 ppm NaCl solution. This work is carried out by potentiodynamic measurements and Electrochemical Impedance Spectroscopy (EIS). The substrates' surface morphologies are examined by Scanning Electron Microscopy (...
