The Rapeseed Oil Based Organofunctional Silane for Stainless Steel Protective Coatings

Abstract

The earlier obtained organosilicon derivatives of rapeseed oil were used for the production of coatings protecting steel surface against corrosion. Vegetable oils have been hitherto used for temporary protection of metals against corrosion, while thanks to the synthesis of appropriate organosilicon derivatives, it is now possible to create durable protective coatings. Due to the presence of alkoxysilyl groups and the use of the sol-gel process, the coatings obtained were bonded to the steel surface. The effectiveness of the coatings was checked by electrochemical methods and steel surface analysis.

Study on Corrosion Characteristics of Aluminum Alloy Al3102 in Sulfate-reducing Bacteria Environment and Investigating the Use of Azadirachta indica Leaves Extract in its Control

“…The φ curve during the first week shows a maximum phase angle value of 77° at the highest frequency and shows a broader MF peak indicating good adsorption of the NLE molecules. The φ at the highest frequency presents a maximum value of 85° for the second week which shows that the maximum thickness of the film is attained in the second week [19]. For the subsequent weeks, the HF region φ drops which indicate the degradation of the protective film and a drop in the corrosion protection effect.…”

Ionic Liquid Modified Electrochemical Capacitor with Long‐Term Performance

“…As suggested by the cited definition, the corrosion phenomenon should be considered as a whole, taking into account various elements of the tested corrosion system, not only the corroding metal itself. Such elements are, for example, other metals present in the solid phase (alloying admixtures, impurities, galvanic coatings), chemical compounds present in the immediate vicinity of the solid phase (e. g. water), including substances that exhibit chemical activity towards these metals (the so‐called corrosive, e. g. H + ions, atmospheric oxygen molecules O 2 ), and other compounds influencing the path and rate of corrosion (e. g. non‐metallic coatings deposited on the metal surface, diffused corrosion inhibitors) [2–10] . Additionally, one should also consider the conditions under which the observed interactions take place (e. g. pressure distribution, temperatures inside the system) [1,2–6,11] .…”
