“…Laser surface treatment is one of the most efficient and versatile surface modification techniques to improve the surface performance of materials when compared with other well-established techniques, such as plasma spraying, ion implantation, as well as physical or chemical vapour deposition (PVD or CVD) techniques [8,9,10]. Since firstly reported by Katayama et al [11], laser nitriding has been proven as a sensible method for enhancing the surface properties of Ti alloys.…”

“…As in typical NiTi-based ternary alloys, Nb plays an important role in NiTi-Nb alloys, because the addition of Nb increases the transition hysteresis of NiTi alloys [10,11]. Moreover, the superior biocompatibility of niobium is conducive to the further improvement of biocompatibility in NiTi-based alloys [12][13][14][15][16][17]. Therefore, there is a strong motivation to develop NiTi-Nb ternary eutectic alloys.…”

“…En múltiples estudios se ha reportado la transformación β→α'' tras el tratamiento superficial por fusión , así como la transformación β→ω, atribuyendo el motivo al enfriamiento rápido que experimenta el material tras alcanzar la fusión (Sun et al, 2003;Yao et al, 2014;Fanton et al, 2020). Zhang y col., quienes trabajaron con la fusión superficial por láser de la aleación β Ti-35Nb-2Ta-3Zr, confirmaron la presencia de precipitados de fase ω con un tamaño aproximado de 2 -11 nm, distribuidos de manera uniforme en la matriz β (Zhang et al, 2019).…”

“…El perfil de dureza de la Figura 5.45 muestra de forma clara como la dureza en la ZF es superior a la dureza del MB en todos los casos. Zhang y col., también reportaron un incremento de 60% de la microdureza en la ZF tras aplicar un tratamiento superficial de fusión por láser mediante el solapamiento de cordones (Zhang et al, 2019). En el estudio, indican un aumento de 165 HV a 264 HV atribuyéndolo a que parte de la fase β con una dureza inferior se transforma en martensita acicular α'' con una dureza superior, y una gran cantidad de dislocaciones y distorsiones de la red se forman en la superficie de la muestra (Wang, Yu, Chen, & Zhao, 2015).…”
