60号钢表面激光碳氮硼合金层的电子显微分析

The element distribution, the phase structure and the microstructure morphology of C-N-B laser-alloyed layer on 60# steel surface were studied by employing the Auger electrom spectrometer, X-ray diffraetometer and the scanning electron microscope. The results show that the laser alloying of C-N-B su
