摘 要：H13 hot work steel samples and surface water vapor oxidized H13 samples were immersed into molten ADC12alloy under static resting or dynamic rotating conditions. Weigh-losing method was used to discover the influences of temperature, time and surface conditions on the erosion resistance of H13 steel. The interfaces between the steel and the molten alloy were studied with optical microscopy to compare the different erosion resistance behaviours. The results show that the composite layer outside of the compounds layers changes obviously with increasing temperature, lasting time or sample movement. The better erosion resistance of H13 steel can be endowed with the oxide films, which would gradually decrease along with the dissolve of the films.
