The principle of spark spectrometer is: it uses the high temperature of arc to gasify the elements in the metal
sampleand stimulate the characteristic wavelength of each element. With the grating, the ‘spectrum’ is
arranged accordingto the different wavelength range.
These characteristic spectral lines of the elements go into therespective photomultiplier tubes through the slit. Then the light signal is transformed into the electrical signal. At last, all the signals are processed by the computer system,and the computer will print out the percentage of each element.

According to the metallography, it establish the quantitative relationship between the alloy composition,
organizationand performance by 3D morphology of the microstructure of the alloy determined by the
measurement and calculation of thetwo-dimensional metallographic specimen surface or the metallographic
micro-structure of thin flms.Test items: chemical elements detection of the casting base, rack.
