MARTINEZ GUTIERREZ, Jeyris; LLUVERAS PEREZ, Emilio Miguel and MARRERO AGUILA, Rigoberto. Behavior of superficial roughness of the steel after natural outdoor and indoor exposure. rev.udcaactual.divulg.cient. [online]. 2019, vol.22, n.1, e1193. Epub May 03, 2019.

Knowledge of the phenomena that take place in the environment that surrounds us, ensures the preservation and proper use of resources, raising the quality of life on the planet for the present and future well-being of the men who inhabit it. One of the natural processes that we face each and every one of the beings that coexist on this planet, whether alive or not, is the deterioration due to interaction with the environment. The most natural form of deterioration in which metals return to minerals, as they are found in nature, is known as corrosion, a process that is affected by multiple environmental factors. The surface condition of a metal sample is an aspect that influences the magnitude and type of corrosion. In the present work we evaluated the behavior of the surface roughness in conditions of natural exposure in exteriors and interiors during a short time of 360 h. Based on the multifactorial design, the incidence of exposure conditions and the test time on surface roughness with a 95% confidence level are demonstrated. The equations of the linear model describe the relationship between surface roughness and exposure time, making possible predictions in the future for climate conditions similar to those described in the study.
