| Abstract: |
| The features of Ni/Zn diffusion dissolution layer formed at powder interface during solid sintering were observed using the technology of powder sintered, optics and electron microscope. The phase of layer was analyzed by energy dispersive spectrum ( EDS) and X-ray diffraction. The formation mechanism of diffusion dissolution layer was discussed by means of Thom-as-fermi-dirac-cheng model. The results show that Zn atoms can diffuse continuously into Ni particles, NiZn and N^Zn^ inter-metallic compounds were formed at the interface of Ni powder and Zn powder during sintering at 200 °C for 15 hours. |
