り成る合金材料が広く用いられていた。(Prior art and its problems) Conventionally, various materials have been used as sliding contact materials, and in particular, as materials for commutators, Au60 to 65 wt% is used.
, 5 to 10 wt% of Ag, and 27 to 33 wt% of Cu have been widely used.
然し乍ら、この合金材料で製作した整流子では刷子との
摺動時の凝着によりｎ１摩耗性が劣り、摩耗粉が生じ易
く、大きな、ノイズの発生の原因となっていた。However, the commutator made of this alloy material has poor n1 abrasion resistance due to adhesion during sliding with the brush, and tends to generate abrasion powder, which causes large noise.
この問題を解決するためにＳｂ、Ｔｅ、Ｐｂ、Ｚｎの一

耗と共に添加元素の酸化物の量が増え接触抵抗が増大す
る傾向がある。In order to solve this problem, alloys containing one or more of Sb, Te, Pb, and Zn may be considered, but they have problems of poor plastic workability and low productivity. Further, with wear, the amount of oxides of added elements increases, and contact resistance tends to increase.
本発明は、斯かる欠点を解消すべくなされたものであり

る。The present invention has been made to eliminate such drawbacks, and uses the above-mentioned alloy as a base material and diffuses and adds specific elements from the surface to suppress adhesion during sliding and improve wear resistance. It is an object of the present invention to provide a sliding contact material that is improved and easy to manufacture.

合金化したことを特徴とするものである。(Means for solving the problem) The sliding contact material of the present invention includes Au60 to 65wt%, Ag
A surface layer consisting of at least one of Sb, Te, Pb, and Zn is provided by plating on an alloy consisting of 5 to 10 wt% and Cu and 27 to 33 wt%, and the surface layer is further diffused to form an alloy. It is something to do.

ずかしいからである。特に乾式めっきでは拡散処理中に
剥がれることがないから好ましい。In the sliding contact material of the present invention, S b % Te,
The reason why the surface layer made of at least one of Pb and Zn was provided by plating is that it is difficult to provide a thin layer in the case of cladding. In particular, dry plating is preferable because it does not peel off during the diffusion treatment.

である。Furthermore, the reason why the surface layer is diffused and alloyed is to suppress adhesion resistance during sliding and improve wear resistance.Also, by creating a concentration gradient of added elements on the surface and inside, wear This is to suppress and stabilize contact resistance, which tends to increase as the temperature increases.

A brush wire rod with a wire diameter of 0.7 mm was made from an alloy consisting of 1 wt%, and this was cut into lengths of 81 mm. Two pieces were placed in parallel and one end was cut into pieces with a width of 10 mm, a length of 13 mm, and a thickness of 0.21 mm. A brush contact was made by welding to the material and bending a 2R arc-shaped contact part at the other end. Then, a brush contact was brought into contact with each disc-shaped commutator, and the commutator was rotated in forward and reverse directions to perform a sliding test under the following test conditions, and the lifespan was measured, as shown in the right column of the table below. I got good results.

触抵抗が低く安定して変わ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: 120 to 130 m/min Contact force: 100 g (blank below) As is clear from the table above, the commutators of Examples 1 to 3 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 contacts. This is simply due to the fact that the sliding contact material of the present invention constituting the commutators of Examples 1 to 3 has Sbs when sliding.
This is because TeXPb and Zn act as lubricants, which improves adhesion resistance and improves wear resistance. In addition, there is a concentration gradient of the added element between the surface and the inside (lowering from the surface to the inside), and the oxide of the added element generated during sliding is easily removed by the sliding action, and as it wears out. This is because the contact resistance is low and does not change stably because it does not increase.

Further, in the above example, the diffusion treatment temperature was 200 to 300°C and the treatment time was 0.5 to 1 hour, but the present invention is not limited to these, and any temperature and time may be used as long as the temperature and time allow alloying without melting. be.
