Bone diseases are still a great concern among patients. Researchers are looking for a material for bone implants that meets all requirements and stimulates cells to grow rapidly. There are various possibilities for the consolidation of ceramic–metal alloys. In the present study, sintering under high vacuums was undertaken. The materials consist of a titanium alloy (Ti6Al4V), which is of course responsible for the strength, and a bioactivity-stimulating agent, hydroxyapatite, so that the bone cells are stimulated to proliferate and form new apatite layers.

The aim of this study was to determine sintering process parameters for titanium alloy and hydroxyapatite composite materials. The obtained matrices were sintered in a vacuum furnace. The materials were subjected to various tests to confirm the correctness of the selected values. Characterization was carried out using various test methods, including XRF, SEM, and microhardness testing. The results so far for the materials obtained show promising potential in the biomedical field. The choice of components and the methods of combining them were appropriate, which prevented the degradation of the samples.
