Title: Production of fine wire for ag-oxide electrical contact
Inventor: OHIRA TOSHIYUKI
IPC: H01H1/023
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To produce a small-diameter fine wire for Ag-oxide electrical contact. SOLUTION: An oxide powder, consisting of one or more kinds among In2 NO3 powder, ZrO2 powder, and CeO2 powder, is mixed with an Ag powder so that it comprises 3-15wt.% of the whole, and mechanical alloying treatment is applied to the resultant powder mixture to form an oxide-dispersed Ag powder. This oxide-dispersed Ag powder is heated to 600-800 deg.C in an oxidizing atmosphere, by which a composite powder, having a two phase structure consisting of oxide- dispersed Ag phases in which fine oxide grains are dispersed and distributed in Ag matrix and precipitated Ag phases, is formed. By applying hot extrusion, forging or foiling, and wire drawing to a press compact of the composite powder, the fine wire for Ag-oxide electrical contact can be produced.
