Use of Hydrogen Heat Treatment in the Production of Porous Materials and Objects Made from Titanium Fiber and Wire

摘要

The possibility is investigated of improving mechanical properties of porous materials made from sintered titanium fibers and wire by hydrogen heat treatment. It is shown that the use of hydrogen heat treatment makes it possible to improve the strength of individually joined fibers and material as a whole. This makes it possible to prepare strong material with a high volume fraction of pores with a cross section of 100-500 mu m and exhibiting good osteointegration capacity. This material is promising for preparing implants, replacing bone defects, or creating functional coatings on endoprosthesis elements.
