Abstract

PURPOSE:To obtain a sliding contact material having superior softening resistance and welding resistance by adding at least one among Co, Sn and Ti to a Pd-Ag-Cu alloy having a specified composition for a sliding contact material. CONSTITUTION:An alloy material obtd. by adding 0.5-15wt% at least one among Co, Sn and Ti to an alloy material having a composition consisting of 30-50wt% Pd, 20-40wt% Ag and 20-40wt% Cu without changing the ratio in the composition is used as a sliding contact material, especially a bursh contact material. A brush contact preventing softening and having superior welding resistance during sliding is obtd.

料を堤供せんとするものである。The present invention has been made to eliminate such drawbacks, and provides a sliding contact that uses the above-mentioned alloy material as a base material and adds a specific material to it to prevent softening and improve adhesion resistance. The purpose is to donate materials.

本発明の摺動接点材料は、Ｐ　ｄ　３０〜５０重量％。The sliding contact material of the present invention has a Pd of 30 to 50% by weight.

By adding 0.5 to 15% by weight of at least one of Co, Sn, and TI to an alloy material consisting of Ag2O to 40% by weight and Cu 20 to 40% by weight without changing the composition ratio. The reason for this is to prevent softening during sliding due to precipitates in order to improve the adhesion resistance of the alloy material.
If it is less than 0.5% by weight, the effect cannot be exhibited, and if it exceeds 15% by weight, the amount of oxides generated increases, contact resistance becomes high, and it becomes unstable.

た処、下記の表の右欄に示すような結果を得た。Next, using the sliding contact material according to the present invention and the conventional sliding contact material having the compositions shown in the left column below, brush wire rods each having a wire diameter of 0.7 tsuru were made, and each brush wire was cut into lengths of 8 tsuru. Then, one end was welded to a base material with a width of 10 mm, a length of 13 fins, and a thickness of 0.2 mm in double rows, and a 2R arc-shaped contact part was bent at the other end to create a brush contact. Ta. Then, each brush contact was brought into contact with a disk-shaped commutator, and the commutator was rotated in forward and reverse directions to perform a sliding test under the following test conditions, and the wear amount and contact resistance were measured. The results shown in the column were obtained.
