The refractory Laves phase TaCr2 of two compositions (series) was synthesized by the metallothermal (hydride-calcium) method from oxide raw materials (Cr2O3 + Ta2O5). synthesis temperature 1200 oC, while excess reducing agent CaH2 varied relative to theoretically required for complete reduction oxides. It is shown that regardless or in its absence, resulting powders have chemical composition (composition 1: calculated Cr content — 37.38% (wt.), actual 37.50±0.85% (wt.); 2:...
In the present study, powder of Ti-18Zr-15Nb biomedical alloy with spongy morphology and more than 95 % vol. β-Ti has been obtained by reduction constituent oxides calcium hydride. The influence synthesis temperature, exposure time, density charge (TiO2 + ZrO2 Nb2O5 CaH2) on mechanism kinetics calcium-hydride β-alloy studied. With help regression analysis, it established that crucial parameters are temperature time; in turn, is considered to be insignificant. Moreover, correlation between...
Medical β-alloys of the Ti – Zr Nb system are promising materials for creating bone implants that do not contain metals toxic to human body. Powder metallurgy makes it possible create porous structures based on this class materials, thereby improving osseointegration tissues. However, shape and size pores in an implant depend morphology initial powder. In light this, effect temperature duration calcium-hydride synthesis phase composition 18 15 (at. %) powder is studied current research. It...
