The present invention aims to provide a sliding contact material.

5 to 15% by weight is added, and further Fe group metal is added in an amount of 0.01 to 15% by weight.
It is made by adding 0.5% by weight.

安定となるものである。In the sliding contact material of the present invention, Nb is added to an alloy material consisting of 30 to 50% by weight of Pd, 40 to 40% by weight of Ag2O, and 40% by weight of Cu2O without changing the composition ratio.
The reason why at least one of In, Ba, and Cd is added by weight of 0.5 to 15% is to generate an appropriate amount of oxide that becomes a lubricant to improve the wear resistance of the alloy material.
If it is less than 0.5% by weight, the amount of oxide generated is small and cannot be effective as a lubricant, and if it exceeds 15% by weight, the amount of oxide generated is large, resulting in high contact resistance (and also It is stable.

The reason why 0.01 to 0.5% by weight of Group E metal is added 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 it exceeds 0.5% by weight? 1! It is a hindrance to oxides that act as lI lubricants.

。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, wires i1Q and 7f were prepared, respectively.
Make a brush wire of i, cut it into 8 lengths each, and make 2
These were arranged in parallel and one end was welded to a composite material having a width of IQ mm, a length of 13 fi, and a thickness of 0.21 mm, and a 2R arc-shaped contact portion was bent at the other end to make a brush contact. 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.

上しているからに他ならない。This is simply due to the fact that the sliding contact material of the present invention, which constitutes the brush wire of the brush contacts of Examples 1 to 7, is
This is because oxides such as n, Ba, and Cd are generated, and these oxides act as lubricants, improving wear resistance. Moreover, since the oxide is soft, it is easily removed by the sliding action, so the contact resistance remains unchanged. In particular, the reason why the amount of wear of the brush contacts of Examples 5 to 7 is even smaller than that of the brush contacts of Examples 1 to 4 is that Fe group metal is added to the sliding contact material of the present invention constituting the brush wire. This is because the crystal grains have become finer and more dispersed, further improving wear resistance.

という効果がある。As detailed above, according to the sliding contact material according to the present invention,
Compared to conventional sliding contact materials, it has significantly superior wear resistance, generates extremely little abrasion powder, and has the effect of providing a brush contact with low and stable contact resistance and almost no noise. .
