Özet

Due to its high strength, stiffness, and biocompatibility, titanium alloys are employed in biomedical applications, although their wear resistance is still inadequate. Porous TiNi structures have a lower elastic modulus and density than dense TiNi structures, but they have sufficient shape memory characteristics, making them suitable for power absorption, lightweight, and biomedical implants. This study investigates the porous Ti-Ni Shape memory alloys (SMAs) tribological behavior for sustainable biomaterial's purposes. The ball-on-disk wear approach with a stainless-steel counter ball was conducted at different speeds times and applied loads to reveal the surface degradation of the Ti-Ni SMAs. The experimental procedure was designed via the Taguchi approach as a design of experimental (DoE) model. The wear mechanisms were inspected according to the wear loss, friction temperature, and worn surface feature. The results revealed that the wear rate and ball depth increased as the speed, time, and applied loads increased. However, the friction temperatures fluctuated according to the wear testing parameters due to the same percentage of the surface samples' surface porosity presence. © 2023 Author(s).
