Abstract

An experimental laboratory investigation of the wear of railroad rail and car wheel materials has shown that increasing the hardness of rails will reduce rail wear but will increase wheel wear. Similarly, harder wheels will reduce wheel wear, but at the expense of increased rail wear. Decreasing relative humidity will substantially increase wear of both materials and will accentuate differential hardness effects. A theory is developed which explains the humidity effects on wear in terms of cyclic plasticity. The increased friction at low humidity brings the subsurface plastic zone to the surface.
