Long-lasting implants (joint prostheses, dental implants), typically made of metals and their alloys, are characterized by improved mechanical properties but low corrosion resistance and biotolerance. Thus, the attempts should be made to develop materials with enhanced functional properties for application in medicine. One of the methods to obtain these materials is to develop composite-based implants that combine good mechanical properties of metallic material with biotolerance of ceramic materials.

The goal of the present work was to develop, by means of powder metallurgy, and to analyse the properties of metal-ceramics composites 316LHC + HA.

Powders of 316LHC stainless steel and hydroxyapatite were used for the investigations (with the composition given in Table. 1). The powders were used to obtain the mixtures containing 0, 20, 30, 50% vol. The samples were then subject to axial compression and the process of sintering at the temperature of 1250⁰C for two hours. The samples were cooled together with the furnace.
