Abstract
Aluminioaren propietate optikoen inguruko ezagutza garatzea beharrezkoa da termografia eta pirometria teknike-tan, zeinak aluminioaren ekoizpena eta saiakuntzak optimizatzeko funtsezkoak diren. Hori dela eta, aluminioarenemisibitatearen neurketa direkzionalak egin dira espektro infragorrian, hainbat tenperaturatarako.Metalenerradiazio teoriarekin bateragarriak diren emaitzak lortu eta literaturan aurki daitezken datuekin alderatu dira.Parekatze horretan ageri diren ezberdintasunak azaltzeko, aztertutako laginaren zenbait parametro (zimurtasunaedota oxido geruza, esaterako) kontuan hartzea beharrezkoa dela ondorioztatu da. Aurretiazko ezaugarritze horrenbitartez, neurketa zehatzagoak egiteko eta aluminioaren propietate optikoen inguruko informazioa osatzeko bideazabaltzen da.
Knowledge about the optical properties of aluminium is critical for the development of thermography andpyrometry techniques, which are essential for optimizing aluminium production and testing. Therefore, directionalmeasurements of aluminium emissivity have been made in the infrared range as a function of temperature.The obtained results, which are compatible with theoretical predictions for the emissivity of metals, have beencompared with the data found in the literature. It was concluded that it is necessary to take into account certainparameters (such as roughness or oxide layer) of the sample analyzed to explain the differences in this comparison.This preliminary characterization paves the way for a more comprehensive and accurate dataset on the emissivityand optical properties of aluminium.
