Ni-Ti MULTIFUNCTIONAL MATERIALS SINTERED VIA CONCENTRATED SOLAR ENERGY

Abstract

This paper presents a study on the solar sintering of Ni-Ti alloys using concentrated solar energy. The sintering process was conducted in a vertical solar furnace, resulting in excellent fusion and controlled microstructures. The evaluation of wetting characteristics and electrochemical behavior provided insights into their performance in aqueous environments. The samples present hydrophilic character and good corrosion resistance, ranging from 2.46⋅10-6 to 3.50⋅10-2 mm/year. The utilization of concentrated solar energy offers sustainable and energy-saving advantages for large-scale production. These findings highlight the potential of solar sintering for tailoring Ni-Ti alloys with desired properties for various applications, including medical devices, energy absorbers, or mechanical couplings.
