When we are testing chemical compounds ( pure component or mixture of comounds such as essential oil) as anticorrosion inhibitor in acidic medium, we are having elctrochemical reactions during the process of evaluation (oxidation, reduction). Can we have other kind of reaction that electrochimical one? chemical reaction forexample ( the action of acid on my component)!
Am I conserving the same testing molecule? Because, we have the factor of acid medium (pH) and the temperature effect which can affect my tested component.
The task of an inhibitor is to significantly reduce the corrosion rate or delay the onset of corrosion. But it must also remain chemically and physically stable over the long term and should not cause any other additional problems. Therefore, one must necessarily pay attention to all possible reactions (chemical, physical and even biological)
Dear Dr. Alexander Sinko ,
the action and use of an inhibitor system are strongly influenced both by the metal substrate, by the plant in which it is inserted (closed or open circuit systems) and by the chemical, physical and biological factors related to the medium in which it is located. operate. In the specific context it is necessary to study both the inhibition mechanism and its efficiency. It is essential that its intrinsic and interacting stability with the substrate are guaranteed. Variations of parameters related to the corrosive medium such as eg. temperature, pH, salt content, dissolved oxygen concentration, any suspended solid particles, etc. both the mechanism and the efficiency of the inhibitor can significantly vary.
Generally speaking, an inhibitor performs an optimal function when it inhibits the corrosive phenomenon by implementing a protection of the substrate in a uniform and stable way over time, both from a morphological and chemical point of view. A non-homogeneous and / or unstable action could have opposite effects.
My best regards, Pierluigi Traverso.
