Abstract
Biocompatible porous materials may find use in the manufacture of bone implant components to facilitate bonding of prostheses with bone tissues. The paper presentsa relatively simple method of producing a porous material from the Ti6Al4V alloy by high pressure hot isostatic pressing (HIP). The process was carried out in capsules made of superplastic alloy. The capsules were filled with a mixture of powdered titanium and a carefully selected salt crystals. The mixing ratios had been calculated from the crystal geometry of the components. The experimental verification of the calculation results defined the mixture component ratios, and the processing program was defined, including the temperature and pressure values for the processing stages. Following the HIP process the capsules were opened and the produced material was cleared of salt and examined to determine porosity, size and geometry of voids, and compressive strength.
