| Abstract: | By means of optical microscope, SEM with EPMA system, x-ray diffraction, TEM and Microhard-ness tester, the compositon, structure and properties of the alloyed zone were determined. The results show that the high temperature hardness and the heat fatigue performance of alloying layer are improved. |
