The present invention aims to provide a sliding contact material with improved wear resistance by adding a small amount of a specific material to the alloy material as a base material.

ｎ、Ｔｉ、ＴＩ。The reason why 0.1 to 3% by weight of at least one type of Zr is added is that sb and I are added to improve the wear resistance of the alloy material.
This is to make it hard by dispersing intermetallic compounds with n, Ti, TI, and Zr, and sb is 1% by weight or In, Ti,
If at least one of TI and Zr is less than 0.1% by weight, the effect cannot be fully exhibited, and if sb is 10% by weight or I
n, Ti, TI.

生量が多くなり、接触抵抗が高くなり、その上不安定と
なるものである。If at least one type of Zr exceeds 3% by weight, the amount of oxides generated will increase, contact resistance will increase, and furthermore, it will become unstable.
また、前記合金材料にｓｂを１〜１０重量％とＩｎ。Further, 1 to 10% by weight of sb and In are added to the alloy material.
Ｔｉ、ＴＩ、Ｚｒの少なくとも一種を０．１〜３重量％

The reason for adding 0.01-0.5% by weight of Fe group metal in addition to the above is to refine the crystal grains and further improve the wear resistance. However, even if the amount exceeds 0.5% by weight, no further effect can be obtained.
次に下記の左欄に示す成分組成の本発明にょる摺動接点
材料と従来の摺動接点材料を用いて夫々線径０．７＋ｕ
ａの刷子線材を作り、これを各々長さ８Ｉ１１に切断し
、２本並列させて一端を幅１−０ｍ＋＋、長さ１３朋５

及び接触抵抗を測定した処、下記の表の右欄に示すよう
な結果をｉ＃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+u.
Make a brush wire rod a, cut each into lengths of 8I11, put two of them in parallel, and one end has a width of 1-0m++ and a length of 13 to 5.
A brush contact was made by welding to a base material with a thickness of 0.2 mm and bending a 2R arc-shaped contact portion at the other end. Then, each brush contact was brought into contact with a disc-shaped commutator, the commutator was rotated forward and backward, and a 7,49 dynamic test was conducted under the following test conditions, and the amount of wear and contact resistance were measured, and the results are shown in the table below. The results shown in the right column of i# were obtained.

0g Test time: 7 hours (4) As is clear from the table above, the brush contacts of Examples 1 to 6 had significantly less wear than the conventional brush contacts, and the contact resistance was equally low and stable. I understand that. This is simply the sliding contact material of the present invention constituting the brush wires of the brush r contacts in Examples 1 to 6, or sb, In, Ti, TI, Z.
This is because the dispersion of the intermetallic compound with r makes it hard and improves wear resistance. In particular, the reason why the amount of wear of the brush contacts of Examples 5 and 6 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 + J material of the present invention that constitutes the brush wire. This is because the crystal grains are made finer and the wear resistance is further improved.
以上詳記した通り本発明による摺動接点材料によれば、
従来の摺動接点材料に比べ著しく耐摩耗性に優れ、摩耗
粉の発生量が極めて少なくて、ノイズの発生が殆んど無

る。As detailed above, according to the sliding contact material according to the present invention,
It has significantly superior wear resistance compared to conventional sliding contact materials, generates extremely little abrasion powder, generates almost no noise, and has contact resistance equivalent to that of conventional sliding contact materials. This has the effect of providing a brush contact point.
