X-ray ,which is excited from the X ray tube, has one wavelength scope, that is energy scope. According to the elements to be analyzed, X ray is choused by filter, and reach the sample. Atoms in the sample will absorb the X ray energy and the decay to emit the special x ray. The X ray will be collected by the collimator into the detector active area, and transferred into electron signal, the signal also will be processed in to energy spectrum and related concentration data by pulse processor with software.

The results showed that the addition of the rare earth alloy powder can refine and disperse oxide particles. Through energy spectrum analysis, it was found that the rare earth congregates to Ti and the interface between metal matrix and diamonds. The active La and Ce in alloy powder can reduce the oxide film on Ti particles, increase the reactivity of Ti, and promote the reaction between Ti and diamond.
