ESTUDIO DE LAS PROPIEDADES DE DESGASTE DE UN TRIBOSISTEMA DE ACERO INOXIDABLE PARA APLICACIONES EN AMBIENTES MARINOS (STUDY OF THE WEAR PROPERTIES OF A STAINLESS STEEL TRIBOSYSTEM FOR MARINE ENVIRONMENT APPLICATIONS)
Resumen
El océano es el principal ecosistema que sostiene y regula el clima en el planeta, genera el 50% del oxígeno de la Tierra y absorbe aproximadamente el 90% del calor generado por emisiones. Permitir que la huella de carbono acabe con este medio ambiente significa renunciar a productos clave para la vida diaria como alimentos, medicinas y biocombustibles, sólo por mencionar algunas de las afectaciones que se tendrían. Para hacer eficiente el uso de los recursos naturales, es imprescindible aplicar los conocimientos de ciencias como la tribología para disminuir la energía que se pierde en un sistema. En el presente trabajo se muestra el análisis de desgaste realizado en un tribosistema de acero inoxidable AISI 316 y AISI 420 para que pueda considerarse como opción en aplicaciones marinas. La caracterización consistió en pruebas de desgaste bajo el método perno-en-disco con cuatro cargas diferentes, el análisis del mecanismo y tasa de desgaste, así como el volumen perdido. Los resultados muestran que el sistema de acero inoxidable puede ser una opción viable para utilizarse en aplicaciones que tengan un rango de carga similar a los ensayados para evitar daños severos en el material.
Palabras Clave: acero inoxidable, ambiente marino, desgaste.
Abstract
The ocean is the main ecosystem that sustains and regulates the climate on the planet, it generates 50% of the Earth's oxygen and absorbs approximately 90% of the heat through emissions. Allowing the carbon footprint to destroy this environment means giving up key products for daily life such as food, medicines, and biofuels, to mention some possible effects. Applying knowledge of sciences such as tribology is essential to efficiently use natural resources to reduce the energy lost in a system. This work shows the wear analysis carried out on a tribosystem of AISI 316 and AISI 420 stainless steel so that it can be considered an option in marine applications. The characterization consisted of wear tests under the pin-on-disk method with four different loads, and the analysis of the mechanism and rate of wear, such as the volume loss. The results show that the stainless steel system can be a viable option to use in applications with loads in ranges as shown to avoid severe damage to the material.
Keywords: marine environments, stainless steel, wear.
