An alloy containing one or more of the following can be considered.
There are problems in that plastic workability is poor and productivity is low. Furthermore, with wear, the amount of oxides of added elements increases, which tends to increase contact resistance.

A surface layer consisting of at least one of B%Si%Ge and Tl was provided by plating on an alloy consisting of 17wt% Ni and 0.5 to 1.5wt% Ni, and the surface layer was further diffused to form an alloy. It is characterized by this.

The reason why the surface layer consisting of at least one of Tl and Tl was provided by plating is that it is difficult to provide a thin layer with Clad. In particular, dry plating is preferred because it does not peel off during the diffusion treatment.

ある。Furthermore, the reason why the surface layer is diffused and alloyed is to suppress adhesion during sliding and improve wear resistance.
This is also to create a concentration gradient of additive elements on the surface and inside, thereby suppressing and stabilizing the contact resistance, which tends to increase with wear.

A brush wire rod with a wire diameter of 0.7 m was made from an alloy consisting of t%, and this was cut to a length of 811 mm, and two home bases were arranged in a row, with one end having a width of 10 mm.
11. A brush contact was made by welding to a composite material with a length of 13 mm and a thickness of 0.2 m, and a 2R arc-shaped contact part was bent at the other end. Then, contact the brush contacts with each disc-shaped commutator,
A sliding test was performed under the following test conditions by rotating the commutator in forward and reverse directions, and the life was measured, and the results shown in the right column of the table below were obtained.

らないからに他ならない。Test conditions Current: 0.6 A Voltage: 12 V Load: Resistance load Rotational speed: 11000 rp Peripheral speed: 130 to 120 m/min Contact force: 100 g (blank below) As is clear from the table above, the commutators of Examples 1 to 4 are conventional examples. It can be seen that the contact resistance is low and stable over a long period of time compared to the commutator. This is simply due to the fact that the sliding contact material of the present invention constituting the commutators of Examples 1 to 4 has B, Si
, Qe, and Tl act as lubricants to improve adhesion resistance. In addition, there is a concentration gradient of additive elements between the surface and the interior (lowering from the surface to the interior), and the oxides of the additive elements generated during sliding are easily removed by the sliding action, resulting in wear and tear. This is because the contact resistance is low and does not change stably because it does not increase with the contact resistance.
