摘要：

The production of highly porous titanium parts of complex shape by powder metallurgical technology is described. Well defined porosity and pore sizes were achieved using a pore forming additive. This additive also enhances the strength of unsintered compacts, allowing machining in the green state. The requirements of the initial powders and pecularities of each production step are discussed in detail. The microstructure of porous materials and examples of net shape parts are given, aiming preferentially at biomedical applications. The impurities of the obtained titanium parts are compared with the requirements of the ISO standard for titanium implants.
