Tribocorrosión: historia, propiedades, aplicaciones y modelamiento

Abstract

La tribocorrosión es el área de conocimiento encarga de estudiar la unión de los fenómenos tribológicos y la corrosión. En esta nota editorial se presenta, a groso modo, aspectos a destacar de la tribocorrosión, se señala la relevancia practica de este campo de investigación para la ciencia de materiales y la ingeniería mecánica. Se relaciona la historia de tribocorrosión, diversas variables a considerar, algunos campos de aplicación identificados y se discute sobre los múltiples desafíos que se presentan en el modelamiento de los sistemas de tribocorrosión.

Determination of the Anticorrosive Properties of Valine and Isoleucine as Ecological Corrosion Inhibitors on AISI 1018 Steel in Sweet Medium

“…The problem of corrosion affects all hydrocarbon industries, as they generate economic losses due to the replacement of structures, pipes, machinery, etc., which deteriorate as a result of this phenomenon, as well as oil losses, the risk of accidents in oil pipelines, human losses, industrial stoppages, environmental pollution, among others (1). Corrosion is the degradation of a material due to an electrochemical attack and in the hydrocarbon industry there are two main types of corrosion: sour corrosion generated by H 2 S (2) and sweet corrosion generated by CO 2 (3). Once a production well does not have enough pressure to pump the crude oil, it is injected with CO 2 and water, due to the effect of the content of CO 2 dissolved in the water, it becomes acid forming carbonic acid and this, in turn, with the oxidation reaction of the iron, becomes iron carbonate, causing fresh corrosion (4).…”
