Abstract
A method of preparation of titanium materials with a porous surface layer by hydrostatic pressing and subsequent high-temperature sintering with use of a pore former as a temporary space holder was proposed. Comparative studies of the structure and properties of titanium materials with a porous surface layer fabricated in a new way and by the classical method of powder metallurgy (uniaxial pressing and high-temperature sintering) were carried out. It was shown that this method makes it possible to obtain porous titanium samples with preset parameters of pore space (volume fraction and pore size) and high mechanical properties. An experimental sample of an endoprosthesis element (acetabular cup) was fabricated using the proposed method.
