| Abstract: | In actual laser forming, it was important to determine the laser absorption coefficient. The temperature field of the aluminum alloy plate without coated with graphite when being scanned by laser beam was measured with thermal imager and thermocouple, and the temperature field was analyzed with finite element method so as to validate the temperature field analysis. The back face temperature field of the plate with graphite coating was analyzed with FEM and the results were compared with the temperature field measured with the thermal imager, then the laser absorption coefficient of the plate coated with graphite was obtained. |
