In this study, the first step was mechanical alloying (M/A) of NiTi+Lax powders via ball milling. Then the alloyed powders were pressed and gradually sintered using airtight ceramic crucibles filled with boron salt (for alloying and creating an atmospheric environment) to obtain NiTi+Lax alloys. The wear properties and behaviors of the samples were determined (with different La amounts (1wt.%, 3wt.%, and 5wt.%)) by pin-on-disc testing. The experiments were carried out at a sliding speed of 1.2 m/s and under 5N, 10N, and 15N loads. The microstructures of the worn surfaces were characterized by FESEM and the distribution of elements was analyzed by EDS. As a result, the lowest friction coefficient and wear loss were observed in the NiTi+Lax alloy containing 1wt.% La. The amount of wear volume increased with the increase in load and La content.}, publisher={Gazi Üniversitesi}, organization={PAMUKKALE ÜNİVERSİTESİ}
