摘要：

The silver base materials containing MgF2 were synthesized by powder metallurgy method. The micro-structures were studied by X-ray diffraction, metallograph and thermal analysis. The hardness, conductance, density and the friction coefficient of materials were tested. The results indicate that the Ag and MgF2 were combined in an atom range with a relative density over 98%, and the conductance of Ag samples added with CaF2 declined obviously; and the grains became thinner obviously. The hardness of material did not obviously increase and and the friction coefficient to Ag and Cu did not obviously decline. In a word, the MgF2 can not be used as the additives of the solid self-lubricating materials.
