Abstract

This article investigates the temperature dependence of electrical resistivity in Ti<sub>41</sub>Zr<sub>41</sub>Ni<sub>18</sub> thin film coatings with varying crystal structures and phase compositions produced by magnetron sputtering and vacuum annealing. It finds that coatings dominated by amorphous, quasicrystalline icosahedral, or 2/1 approximant phases exhibit a negative temperature coefficient of resistance (TCR), while those with predominantly crystalline phases show metallic conductivity with positive TCR. The temperature-dependent resistivity behavior of the quasicrystalline phase in films closely matches that of bulk Ti<sub>40</sub>Zr<sub>40</sub>Ni<sub>20</sub> samples. Additionally, films with a 2/1 approximant phase and low Laves phase content display nearly constant resistivity across 4 to 300 K. These results highlight the influence of phase composition on electron transport properties in Ti-Zr-Ni alloy coatings.
