COMPLEX-RELUCTANCE PLANE BEHA VIOR OF ALUMINUM SAMPLES Otto
نویسنده
چکیده
Coil eddy-current (CEC) technology generatesreal and complex reactances ofthe search coil. These reactances are frequently plotted in a complex-impedance (C-1) plane with inductive reactance as the ordinate and resistance as the abscissa. This plane is a useful tool in nondestructive evaluation (NDE), and it is known to virtually all NDE technicians using electromagnetic fields. The complex-impedance plane is generally used to establish the operating conditions for particular eddy-current coils and for particular NDE problems. lt can also be used to establish the effect oflift off and to identify flaws.

Adsorption Behavior of Surfactant Mixtures at Solid-Liquid Interface
Behavior of surfactant mixtures at solid-liquid interfaces was investigated using anionic-nonionic and catjonic-nonionic surfactants of different structures. The results show that adsorption of nonionic surfactants on alumina was enhanced significantly by the coadsorption of ionic surfactants. The adsorption beha vior of these binary surfactant mixtures was dependent upon the ratio of the two s...
