Abstract

PURPOSE:To improve the wear resistance of the resulting sliding contact material by adding small amounts of Mn and one or more among In, Sn, Sb, P, Ti and Zr to an alloy material having a specified composition consisting of Au, Ag and Cu. CONSTITUTION:This sliding contact material is obtd. by adding, by weight, 1- 10% Mn and 0.1-3% one or more among In, Sn, Sb, P, Ti and Zr to an alloy material consisting of 61.5-63.5% Au, 28-30% Ag and 7.5-9.5% Cu without changing the ratio in the composition. To the alloy material may be further added 0.01-0.5% Fe group metal. This sliding contact material has superior wear resistance and can give a brush contact having contact resistance equal to that of a brush contact made of a conventional sliding contact material.

The reason why 0.1 to 3% by weight of at least one of P, Ti, and Zr is added is to improve the wear resistance of the alloy material.

If at least one of p, Ti, and Zr is less than 0.1% by weight, the effect cannot be fully exhibited, and if Mn is more than 10% by weight or In, Sn + at least one of Sb, P, Ti, and Zr is more than 3% by weight. The amount of oxides generated increases, the contact resistance increases, and furthermore, it becomes unstable.

0.1 of at least one of Sn, Sb, P, Ti, and Zr
In addition to adding ~3% by weight, 0.01 ~ Fe group metal was added.
The reason why 0.5% by weight 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, but if it exceeds 0.5% by weight, the effect of grain refinement will not appear. This is because no further effect can be obtained.

Test conditions Current: 0.6A Voltage = 12■ Load: Resistive load Rotation speed: 1000 rpm Peripheral speed
: 130-120 m/min contact crab
100g Test time: 7 hours (blank below) As is clear from the table above, the brush contacts of Examples 1 to 7 had significantly less wear than the conventional brush contacts, and the contact resistance was equally low and stable. I know that there is. This is because the sliding contact material of the present invention constituting the brush wire of the brush contacts of Examples 1 to 7 contains Mn, In, Sn, Sb, P, and T.
This is because the dispersion of intermetallic compounds with Zr and Zr makes it hard and improves wear resistance. Especially Example '1
The reason why the amount of wear of the brush contacts is much smaller than that of the brush contacts of Examples 1 to 6 is because the Fe group metal is added to the sliding contact material of the present invention, which constitutes the brush wire, and the crystal grains are made finer. This is because the wear resistance has further improved.

This has the effect of providing a brush contact point.
