    摘要： A method for manufacturing an electric contact material is provided which can prevent it from being adhesively melted even when being exposed to high temperatures resulting from an arc induced by an electric current being turned on or off. Also an electric contact material which is manufactured by the method and a thermal fuse are provided.A surface layer portion of an alloy containing 1 to 15 mass % of Cu, 0.01 to 0.7 mass % of Ni, and the remainder of Ag and unavoidable impurities is supplied with an amount of oxygen exceeding the amount of oxygen required for internal oxidation of Cu to form an oxygen concentrated layer. This alloy can serve as an electric contact material.This electric contact material is formed into a movable electrode, which is in turn employed for a thermal fuse.

    摘要： The present invention is aimed at providing a sliding contact material that has an alloy composition containing no harmful substance like Cd, especially excellent contact resistance properties, electrical functions that are good and is not subject to secular change, and abrasion resistance practically bearing comparison with conventional sliding contact materials, and is aimed at lengthening the life of a motor by the use of a sliding contact material having excellent durability as a commutator for a small direct-current motor. The present invention is a sliding contact material of an Ag—Ni-based alloy that is used in sliding part electrically switching on and off by mechanical sliding action, and the material is a sliding contact material of Ni metal particle-dispersed-type Ag—Ni-based alloy that is produced in such a method that 0.7 to 3.0 wt. % Ni powder, an additive of Li2CO3 powder corresponding to 0.01 to 0.50 wt. % Li after being converted to metal and the balance of Ag powder are mixed and stirred to form a uniformly dispersed mixture, then the mixture is treated with forming and sintering processes.

    摘要： A target consisting essentially of a CoCrPt-based metal or a CoCrPtRu-based metal, and one or more metal oxides selected from the group consisting of SiO2, Cr2O3, CoO, TiO2 and Ta2O5, is heated in an upper crucible of a two-level crucible that includes the upper crucible with a through hole formed in a bottom surface, and a lower crucible disposed below the through hole. The target is heated at a temperature of from 1400 to 1790° C. if the target does not contain both TiO2 and Ta2O5. The target is heated at a temperature of from 1400 to 1630° C. if the target contains TiO2 but does not contain Ta2O5. The target is heated at a temperature of from 1400 to 1460° C. if the target contains Ta2O5. The metal thereby melted is caused to flow into the lower crucible, so that the metal is separated from the metal oxide.
