Surface potentials of corona-charged ferroelectric P(VDF-TrFE) copolymer samples
(Ferroelectrics, 1993-01-01) [Artigo]
Surface potential measurements are presented as a function of time for negatively corona charged P(VDF-TrFE) samples in a constant current corona triode kept at low humidity levels. The surface potential curves roughly ...
Morphological study of nitrides of NbTi (50:50, by weight) alloy
(Journal of Alloys and Compounds, 1993-04-13) [Artigo]
Plates of NbTi (50:50, by weight) were nitrided in a nitrogen atmosphere in the temperature range 800-1000 °C for 15, 30, 60, 120 and 180 min. X-Ray diffraction and optical and electronic microscopy were used to characterize ...
