Wettability Behavior of Ti6Al4V Electron Beam Melted Surfaces

Article Preview

Abstract:

The contribution of the present work is to experimentally evaluate the wettability of Ti6Al4V solid surfaces manufactured via Electron Beam Melting (EBM), an innovative Additive Manufacturing (AM) process. The wettability behavior was quantified via goniometer, measuring the contact angle between a carefully deposited liquid drop (distilled water) and suitable solid surfaces. In order to study the influence of orientation and location in the build chamber on such properties several specimens were EBM manufactured with different growing direction.
