Tartalmi kivonat:The mechanical characteristics and electrochemical behavior of the new titanium alloys TiMoZr, TiMoZrSi0.5, TiMoZrSi0.75 and TiMoZrSi1 were studied to determine their microstructure, corrosion behavior and mechanical properties. Following the use of the appropriate procedures, metallographic analysis showed that both samples had biphasic and dendritic structures. According to electrochemical tests in body simulation fluid, the samples' corrosion resistance increases with decreasing silicon content since silicon-containing samples corrode more quickly. Electrochemical Impedance Spectroscopy measurements were performed at various potentials, and the acquired spectra show a two-time constant system, due to the presence of a double-layer passive film on the samples. The three-point bending test for both samples demonstrated that the values of modulus of elasticity are lower than those commercial alloys and nearly to the cortical human bone, and the microhardness test showed that the samples' surfaces had soft and hard phases.
