Monitoreo de la tasa de corrosión en probetas metálicas utilizando diferentes métodos de protección en la Empresa ADELCA del cantón Milagro

Abstract

In the industrial sector, there is no data about the corrosion rate of structural steel in an aggressive (warm) environment; for this reason, the need arose to perform an analysis of the corrosion rate. Therefore, the objective of this research was to establish the experiment station on the corrosion rate in metal specimens with different protection methods at the ADELCA company in the Milagro canton, province of Guayas. The methodology for the research was through descriptive statistics with data obtained from four groups of specimens, one group without a protection method and three groups with protection methods such as zinc coating, surface coating, and cathodic protection by sacrificial anode. In addition, a container capable of supporting the electrolyte (earth) and each group of test tubes with their respective anti-corrosion protection method was created. The R-Studio software was used for the statistical analysis, which facilitated the data analysis. In addition, the corrosion rate was variable depending on the conditions to which the structural steel was subjected. This speed became null while the protection method lasted. In this context, it is concluded that the average speed of black steel without any anticorrosive protection is 0.0030647 mm/year. In comparison, in galvanized steel, a speed of 0.000398881 mm/year was obtained, which helped to identify the duration of the coating of the structural steel before its aggressive corrosion begins; this will help in rapid intervention before there is a significant consequence due to corrosion.
