Because of its high reactivity, ultrafine powder of the alloy Zr (16 wt.%)–Fe (9 wt.%), which is used for the production of a solder paste for the brazing of ceramics, must be conditioned for a safe handling. The conditioning methods, hydrogenation

Alloys based on titanium or cobalt have been used as implant materials for decades with good success. Because of their natural oxide layer these alloys reveal good corrosion behaviour. In contact with physiological solution metal release takes place,
