Also several groups applied a similar approach to increase the open porosity of lters.10-13 Recently, this technology The production of highly porous titanium parts of has been used for biomedical applications,14 but until now complex shape by powder metallurgical technology is the technique was restricted to the production of parts with described. Well de ned porosity and pore sizes were simple geometry such as cylinders or bars. In contrast to achieved using a pore forming additive. This additive this, many titanium parts, for example surgical implants, also enhances the strength of unsintered compacts, have a high complexity in the shape. allowing machining in the green state. The require-The present work focuses on the development of a ments of the initial powders and pecularities of each suitable manufacturing route for net shape parts made of production step are discussed in detail. The microhighly porous titanium, while the mechanical properties structure of porous materials and examples of net and deformation behaviour of this material have already shape parts are given, aiming preferentially at biobeen published elsewhere.8,9 Considering that the quantity medical applications. The impurities of the obtained of implants with speci ed size is usually small, the applititanium parts are compared with the requirements of cation of special dies and automated equipment becomes the ISO standard for titanium implants.
