Study of Electrochemical and Biological Characteristics of As-Cast Ti-Nb-Zr-Ta System Based on Its Microstructure

The quaternary Ti-Nb-Zr-Ta (TNZT) alloy was successfully cast-fabricated with the objective to be used in medical field. Samples’ microstructure compared CP-Ti and Ti-6Al-4V (control samples) related corrosion, ion release biological properties. As-cast TNZT formed large β grain sizes (285 µm) ultrafine α of (11 + 1.45 µm 0.74 µm. Hardness flexural elastic moduli (94 HV 43 GPa) came close structures, such as dentin enamel values. mechanism as-cast significantly lesser than Ti-6Al-4V, which can difference samples’ chemical compositions. However, corrosion rate higher for control samples; this way offers properties inferior respect obtained reference materials. Biological assays demonstrated that two-cell (hDPSCs MG-63) lineage studied presented good adhesion capability differentiate bone cells on surface, no cytotoxicity effects were found. Details reasons based are discussed.
