It is made by adding 0.5 to 15% by weight of at least one of Nb, In, Ba, and Cd to an alloy material consisting of 29 to 31% by weight without changing the composition ratio.

くなり、その上不安定となるものである。In the sliding contact material of the present invention, Au 19-21% by weight, PL 4-6% by weight, Pd 44-46% by weight, Ag
The reason for adding 0.5 to 15 weight % of at least one of Nb, In, Ba, and Cd to the alloy material consisting of 29 to 31 weight % without changing the composition ratio is that This is to generate an appropriate amount of oxides that act as lubricants to improve wear resistance. If the amount is less than 0.5% by weight, the amount of oxides generated is too small to be effective as a lubricant, and if it exceeds 15% by weight. This results in an increased amount of oxides, increased contact resistance, and instability.

E group metal 0. The reason for adding 1 to 0.5% by weight of O is to refine the crystal grains and further improve the wear resistance.If it is less than 0.01% by weight, the effect of grain refinement will not appear, If the amount exceeds % by weight, the oxide acting as a lubricant becomes a hindrance.

した処、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, each wire diameter was 0.7 t.
Make a brush wire of m length, cut it into 8 lengths each, and cut it into 2 pieces.
These are lined up and one end is 10mm wide, 13N long, and 0.2mm thick.
A brush contact was made by welding to a base material of 2R and bending a 2R arc-shaped contact part at the other end. 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.

00g Test time: 7 hours As is clear from the table above, the brush contacts of Examples 1 to 7 have significantly less wear compared to the conventional brush contacts, and it can be seen that the contact resistance is equally low and stable. . This is simply due to the fact that the sliding contact material of the present invention constituting the brush wire of the brush contacts of Examples 1 to 7 has Nb, In, Ba,
This is because oxides such as Cd are generated, and these oxides act as lubricants, improving wear resistance. Also, since the oxide is soft, it is more easily removed for sliding action, so the contact resistance remains unchanged. Especially Example 5
The reason why the amount of wear of the brush contacts of Examples 1 to 7 is even smaller than that of the brush contacts of Examples 1 to 4 is that group 1.e metal is added to the sliding contact material of the present invention that constitutes the brush wire. This is because the crystal grains are fine and dispersed, which further improves wear resistance.
