“…Furthermore, the relative density decreased because of an increase in porosity, which serves to increase the electrical resistance. The electrical percolation phenomenon [12][13][14][15] caused by the addition of CNTs to the ceramic matrix composite, particularly in the range of 3 to 6 vol. % CNTs.…”

“…Therefore, one way to take advantage of ceramics while compensating for these defects is to produce ceramic/CNT composites. ZrO 2 /CNT composites have been reported by several authors [12][13][14][15][16]. However, the effectiveness of CNTs on the properties of the ceramic composites is still matter of debate [15][16][17][18].…”

Zirconia matrix ZrO 2 /CNT composite materials reinforced with multiwall carbon nanotubes were fabricated using a spark plasma sintering technique. The effects of the amount of CNTs addition, sintering temperature and sintering pressure on the properties of the resulting ZrO 2 /CNT composites were examined. 0 to 9 vol. % CNTs were dispersed in zirconia powder, and the resulting mixture was sintered. The electrical conductivity, hardness, flexural strength, and density were measured to characterize the composites. The friction and wear properties of the composites were also tested. The flexural strength and friction coefficient of the composites were improved with up to 6 vol.% of CNT addition and the flexural strength showed a close relationship with the relative density of the composite. The electrical conductivity increased with increasing proportion of the CNTs, but the efficiency was reduced at more than 6 vol.% CNTs.

The paper is a review of original results, which were obtained by mechanical spectroscopy in the development of industrial materials, such as grey cast iron (damping capacity), aluminum alloys (recrystallization), nickel alloys (grain boundary embrittlement) and gold alloys (hardening mechanisms). Moreover it is shown that the study of grain boundary sliding at high temperature has led to the development of new grades of zirconia exhibiting a high toughness and a good resistance to creep. It is also recalled that mechanical spectroscopy has been a mandatory technique in the development of light metallic materials, which exhibit simultaneously good mechanical properties and a high damping capacity, and are consequently well suited to transport means.Keywords: mechanical spectroscopy, internal friction, damping capacity, industrial materials Artykuł prezentuje przegląd oryginalnych wyników, które zostały uzyskane za pomocą spektroskopii mechanicznej podczas rozwoju materiałów przemysłowych, takich jak żeliwo szare (zdolność tłumienia), stopów aluminium (rekrystalizacja), stopów niklu (kruchość granic ziaren), i stopów złota (mechanizmy umocnienia). Ponadto pokazano, że badania poślizgu granicy ziaren w wysokiej temperaturze umożliwiły rozwój nowych gatunków tlenku cyrkonu wykazujących wysoką wytrzymałość i dobrą odporność na pełzanie. Przypomniano także, że spektroskopia mechaniczna jest obowiązkową techniką stosowaną w rozwoju lekkich materiałów metalowych, które wykazują jednocześnie dobre właściwości mechaniczne oraz wysoką zdolność tłumienia, a tym samym są odpowiednie do zastosowania w środkach transportu.
