Abstract: AgTiB2 contact material with different additives was prepared by high-energy
milling and powder metallurgy. The effects of WO3, Al, Bi2O3 addition and WO3+Bi2O3, WO3+Al
composite additions on the microstructure and properties of AgTiB2 were investigated. The
morphology of milled powders and the microstructure of AgTiB2 composite with different
additives were characterized by scanning electron microscope equipped with energy disperse
spectroscopy, and the hardness and electrical conductivity were tested. The results show that
WO3single addition and WO3+Al, WO3+Bi2O3 composite additions can improve the densification
of AgTiB2. In comparison with those of Ag/TiB2 composite without any additive, the hardness
and electrical conductivity of the AgTiB2 composite materials with WO3 single addition and
WO3+Al composite addition are increased, whose hardness values are 1253 and 1022 MPa
respectively, and the electrical conductivity are 78.62%IACS and 14.91%IACS, respectively. The
hardness and electrical conductivity of the AgTiB2 composite materials with Bi2O3+WO3
composite addition are 786 MPa and 16.12%IACS, respectively. © 2012, Northwest Institute for
