Özet
The microstructural, mechanical, corrosion properties, and wear behaviors of as-cast Mg-Sb-based alloys with various La contents (0, 1, 2, and 4 wt.%) were investigated. The microstructural properties were analyzed by x-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). The tensile and microhardness tests were carried out to examine the mechanical properties. Corrosion properties were investigated in 3.5 wt.% NaCl using both electrochemical and immersion tests. Wear tests were carried out at three different loads of 10, 20 and 40 N and at three different sliding speeds of 0.3, 0.6 and 1.2 m/s. The results showed that the Mg-Sb alloy had alpha-Mg and Mg3Sb2 phases, and La4Sb, LaSb and Mg17La2 phases were formed by the addition of La. The yield strength and hardness continuously increased along with the increasing La content, while tensile strength and ductility first increased and then decreased by the addition of 2 wt.% La. It was observed that the corrosion resistance improved by the addition of 1 wt.% La, and the addition of more La worsened the corrosion resistance, and the best wear rate was obtained by the addition of 1 wt.% La.
