Abstract
PURPOSE: To provide an electric contact material having excellent resistance to deposition and less consumption by a method wherein high-hardness heat stable WC powder is added to mixed powder of Ag and Ni powder and sintered.
CONSTITUTION: Mixed powder of 10W15wt% of carbonyl Ni powder with 290 mesh or less size, 0.5W10wt% of fine WC mixture of 1μm or less and 5μm or less, and the remaining electrolytic Ag powder of less than 200 mesh is mixed in V-type mixer for 20hr. The mixed powder is compressed and formed in vacuum under a pressure of 2W8ton/cm2 and sintered in a reducing atmosphere or vacuum for 4 hours to provide a Ag-Ni-WC based electric contact material. In this manner, high- hardness heat-stable WC particles are uniformly distributed within Ag base, so that an electric contact material excellent in resistance to deposition and less consumption is provided.
