Abstract
The wear loss for 60 : 40 brass plate sliding on the steel shaft has been measured. The test apparatus is of such a type that the edge of brass plate finished straight may be loaded on the rotating steel shaft. Therefore the contact pressure decreases gradually with the wear of the sample, but there will be no objection to the fact that the wear loss coincide with the wear by the instantaneous pressure.
The wear loss is maximum at the speed of about 2cm/s, and decreases with increasing speed.The alloys containing much Pb wear to a high degree, but those reduced highly by rolling, wear to a low degree.
