<P>PROBLEM TO BE SOLVED: To provide a method for measuring carburized depth of a Cr-containing alloy capable of simple measurement and quantitatively grasping the carburized depth without destroying a measuring object. <P>SOLUTION: A plurality of samples of a Cr-containing alloy having different carburized depths are analyzed by a portable type fluorescent X-ray analyzer (step S2), and a relation between concentrations of chrome and metal elements other than chrome and carburized depth is previously determined (step 4). Then, a Cr-containing alloy which is a measuring object is analyzed by the portable type fluorescent X-ray analyzer and concentrations of chrome and metal elements other than chrome in the measuring object are measured (step S6). After that, based on the previously determined relation, carburized depth of the measuring object is determined from the measurement result of the concentrations of chrome and metal elements other than chrome in the measuring object (step S8). <P>COPYRIGHT: (C)2012,JPO&INPIT |
