Abstract
The Research on the wear of copper alloy bearings is, at present, being continued. This is a report on the wear of brass bearings.
The results obtained were as follows:
1. The effect of rubbing condition.
At a comparatively high speed, wear was stable, but as a speed became lower, wear increased gradually and it was maximum at the velocity of 1-2mm/s. As to the rubbing pressure, wear was almost proportional to the pressure.
2. The effecct of adding elements (Al, Si, Fe, Sn, Pb, etc.)
By adding Al, Si, Ni, or Fe, brass bore wear-resisting property, but when Sn or Pb was added, wear increased remarkably.
3. The effect of mechanical property.
The impact value and the high temperature hardness (500°C) seemed to have relation considerably with wear, but these are still under experimentation.
