Effect of magnetoelectropolishing on nanohardness and Young's modulus of titanium biomaterial

Nanoindentation studies were performed on CP-titanium biomaterial after its treatment under a standard electropolishing (EP) and magnetoelectropolishing (MEP) conditions, with abrasive finishing (MP) carried out on the samples for reference. The Young's modulus of elasticity and nanohardness were investigated. The mechanical properties of titanium biomaterial demonstrated an evident dependence on the surface treatment conditions. After magnetoelectropolishing (MEP) treatment a considerable deviation in mechanical properties of the same Ti biomaterial is observed in comparison with the mechanical properties obtained from the samples after abrasive finishing (MP) and a standard electropolishing (EP).

► Mechanical properties of titanium are dependent on electrochemical treatments.
► Dependence on electropolishing (EP) conditions is evident.
► Magnetoelectropolishing considerably improves mechanical properties of titanium.
► Statistics confirm significance of our results presented.
► Nanoindentation results are in agreement with author's earlier findings.
