Abstract
Titanium alloys, due to their exceptional mechanical properties and biocompatibility, are commonly used to produce medical implants nowadays. However, the presence of such elements as aluminium and vanadium can be harmful to human health. One of the possible solutions could be replacing the titanium alloys with commercially pure titanium (cpTi) with highly refined grain structure. One of the most promising methods in manufacturing medical implants with improved biological fixation is laser cladding in which bioactive glass coatings
are imposed on metallic substrates. The aim of this work is to present a 3D numerical modelling of the above mentioned additive manufacturing process. The obtained model is able to predict the stress-strain and temperature distributions as well as porosity degree during the processing. Porosity affects the bioactivity of medical implants as it significantly improves their ability to bonding with host tissues.
