Original abstract
There are two types of experimental materials used pure nickel and its nanocomposite reinforced by nano-sized SiO2. These materials were produced by TU Clausthal, Germany. The material was deposited on copper substrate by electrodeposition under these conditions: direct current, 25 mA and 30 h. After electroplating, the copper substrate was metallographically ground out to obtain free-standing samples for the creep testing. The creep tests were carried out at temperatures from 293 to 573 K and the applied stress ranged from 125 to 700 MPa. Fracture details were observed by scanning electron microscope PHILIPS XL 30
Czech abstract
Nanostrukturní čistý nikl a jeho nanokompozit byly připraveny elektrolytickým pokovováním na měděném substrátu za těchto podmínek:stejnosměrný proud 25mA, 30hod. Měděná podložka byla mechanicky odstraněna a tím byl získán experimentální materiál pro mechanické a creepové zkoušky. Předmětem studia bylo srovnání tahových a creepových vlastností elektrolyticky nanášeného čistého niklu a jeho kompozitu s nanometrickými částicemi SiO2. Creepové zkoušky byly provedeny v rozsahu teplot od 293K do 473K. Experimentální materiál (Ni a Ni+SiO2) byl studován pomocí REM a TEM. Studium bylo především zaměřeno na rozložení částic SiO2 v matrici a velikost zrn matrice i částic.
