Título: | Detection of metallic cylindrical inclusions by thermoelectric coupling |
Autor: | Carreón, H.; González-Carrasco, José Luis CSIC ORCID CVN | Fecha de publicación: | 2012 | Editor: | Sociedad Mexicana de Física | Citación: | Revista Mexicana de Fisica 58: 372-377 (2012) | Resumen: | In this paper, we present a technique that can give information on surface metallic inclusions embedded in a host material, i.e. by the magnetic sensing of local thermoelectric currents produced when a temperature gradient is established in the material. These thermoelectric currents generate flux magnetic densities that are detected by a highly sensitive magnetometer. A comparison between reported analytical results with experimental data of the magnetic field produced by thermoelectric currents around surface-breaking cylindrical tin inclusions in copper under external thermal excitation for different lift-off distances between the sensor and the surface of the specimen is presented. The diameter of the inclusions varied from 4.76 to 12.7 mm at different lift-off distance magnetometer probe and the specimen 1 to 8 mm respetively. A fairly modest 1.46°C/cm temperature gradient in the specimen produced magnetic flux densities ranging from 60 to 1460 nT. | URI: | http://hdl.handle.net/10261/76739 | Identificadores: | issn: 0035-001X http://rmf.smf.mx/pdf/rmf/58/5/58_5_372.pdf |
