Preservative materials based on vegetable oils for steel protection against atmospheric corrosion. I. Colza oil

Abstract

The protective efficiency of a formulation based on low erucic colza oil against carbon steel corrosion in salt solution (0.5 M NaCl), in a thermal moisture chamber and under natural conditions has been studied. The following formulations have been used: (1) colza oil (CO) without inhibiting additives; (2) CO with addition (1-10 wt.%) of synthetic fat acids bottoms (SFAB); and (3) CO with the IFHAN-29A anticorrosion additive (20 wt.%). Corrosion tests and electrochemical measurements have been conducted. Protective CO coatings are not efficient in the presence of chloride ions but provide a high protective efficiency under natural conditions.

Use of laser correlation spectroscopy to investigate the parameters of biological suspensions

“…11 This method was also shown in a number of papers to be informative when technical solutions and suspensions are investigated. [12][13][14][15][16] At the second stage of the project, we investigated solutions of albumins in distilled water. The character of the dynamics of the protein analytes was investigated by recording the total intensity and by visual observation using ultramicroscopy.…”

Inhibition of corrosion of L 80 alloy in sodium hydroxide solution (pH=12) by succinic acid

“…The corrosion resistance of L80 alloy in sodium hydroxide solution (pH = 12) has been measured by electrochemical studies such as potentiodynamic polarisation study and AC impedance spectra [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28].…”

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.…”
