Abstract

Obtaining of an appropriate implant material requires a detailed analysis of the effect of the applied surface treatments. In the particular study, the Ti5Al4V alloy was vacuum heat treated and electron beam surface modified (EBSM) by scanning electron beam and its surface characteristics were revealed by modern topographic and metallographic analysis. The studies provided an essential insight into the change of the surface characteristics – topography and surface roughness, as well as the transformations of the structure caused by the vacuum heat treatment (solution treatment and precipitation) and the subsequent EBSM. The results from the SEM, AFM, and profilometry analyses after the EBSM of the as-received, quenched and precipitated Ti5Al4V alloy were compared. The obtained results are indicative of the alloy ability to modify the desired structure, appropriate for biomedical applications.
