u8-12% by weight, Ag27-33% by weight, Cu1
The reason why the alloy material is composed of 2-16% by weight of ZnO and 1-2% by weight of ZnO is to take advantage of its excellent spring properties.In addition, in the composition of a commutator or slip ring material, 0.0% of Ag is used. The reason for adding 1 to 5% by weight of C is
This is to improve wear resistance by suppressing adhesion during scraping operations, and if it is less than 0.1% by weight, this effect will not be apparent, and if it exceeds 5% by weight, processing will become difficult. 3 more n
The reason for adding 0.5 to 10% by weight of at least one of 7'i and 7'i is to increase the softening temperature during the rubbing action with the brush and improve wear resistance. If the amount exceeds 10% by weight, the amount of oxides generated increases, contact resistance becomes high, and furthermore, it becomes unstable.

した処、下記の表の右欄に示すような結果を得た。On the other hand, a plate material with a thickness of 0.5 m made of the materials of the embodiments and conventional examples having the composition shown in the left column of the table below was punched out to have a diameter of 5 m.
I made a 0n slip ring. Therefore, a sliding contact device was made by combining these brushes and slip rings, respectively.
The brushes were brought into contact with the slip rings, and the slip rings were rotated in forward and reverse directions to conduct abrasion tests under the following test conditions.The wear amount and contact resistance of the brushes and slip rings were measured, and the results are shown in the right column of the table below. We obtained the results shown below.

100g Sliding operation time Near time As is clear from the table above, the brushes and slip rings of the sliding contact devices of Examples 1 to 3 have a greater amount of wear than the brushes and slip rings of the sliding contact devices of Conventional Examples 1 and 2, respectively. It can be seen that the contact resistance is low and stable. This is because the materials constituting the slip rings of the sliding contact devices of Examples 1 to 3 are made of C to suppress adhesion, and Sn and Ti.
This is because the wear resistance is improved due to the increase in the softening temperature due to the addition of one type of steel, and the amount of oxides generated during the rubbing operation is balanced with the amount of wear.

It can be said that it can replace the sliding contact device.
