Abstract:

The effect of temperature on the erosion of metals by solid particles is studied. Properties that, as the temperature increases, decrease the metals' resistance to erosion (Type I) are identified, as are other properties that increase their resistance to erosion (Type II). The removal of erosive material is accomplished through the simultaneous action of several mechanisms. Under given test conditions (such as angle of impact, particle shape, and hardness) one mechanism is likely to dominate. Whether erosion increases or decreases as the temperature increases depends on the dominant erosion mechanism because some mechanisms are affected by Type I factors while others are affected by Type II factors. This dependence may change, however, at various ranges of the temperature scale. At homologous temperatures (the ratio between the actual temperature of the material and its melting temperature, in absolute degrees) above 0.5, Type II factors dominate most erosion mechanisms. Of particular interest are the brittle-to-ductile transition temperature and the recrystallization temperature.
