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

Abstract

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).
