Abstract
PURPOSE: To obtain a composite electrical contact material with superior contact performance and melt-sticking resistance by internally oxidizing an alloy prepared by adding a specified amount of Cd and Bi to Ag.
CONSTITUTION: An alloy prepared by adding 20W30W/O Cd and 0.01W2W/O Bi to Ag is melted and sprayed. The resulting fine grains are internally oxidized in an oxygen atmosphere at about 900°C under about 9 atm to obtain composite powder of Ag-CdO-Bi2O3. At this time, all of the Cd in the fine grains is oxidized by the effect of the added Bi. The composite powder is compressed and sintered, and the sintered body is extruded and drawn into a wire rod, which is then headed to manufacture a rivet type electrical contact. To Ag may be added 0.01W1W/O Ni besides Cd and Bi.
