Abstract
The effect of 0.2, 0.4, 0.6, 0.8 and 1.0 wt.% P on the dry sliding wear of a grey cast iron using a steel-pin-on-ring technique with a speed of 1.5 m s −1 and mean normal stresses of 0.5, 1.0, 1.5 and 2.0 MPa has been investigated. A uniform pattern of wear behaviour occurred. Severe wear of the 0.2 wt.% P iron occurred at all stresses. The presence of phosphorus reduced the wear rate progressively at all stresses; at the lowest stress 1.0 wt.% P results in the most mild wear and at the highest stress all irons suffered severe wear. Metallographic features of the surfaces and sections are related to the results.
