Abstract

It has been studied the influence of processing parameters on the superficial oxidation and mechanical properties of different coatings of Ti6Al4V. The high chemical reactivity of titanium powder, and the high temperature reached during laser processing, produces a great variety of colors in the oxides formed. This oxidation can have a detrimental effect on the behavior in service so that its evaluation is essential. Although the influence of processing on the color of the oxides formed is clear, there is no simple relationship to explain its mechanical properties. For this reason it has been applied a methodology based on microscopy, microanalysis wavelength spectroscopy (WDS) and nanoindentation. The results indicate no significant differences in hardness and elastic modulus between two coatings with different colors of oxidation.
