摘要：
The microstructures and properties of coating from cemented carbide on the substrate of H13 by vacuum powder sintering were studied. The effect of sintering temperature on the microstructures of coating was discussed. The interface characteristics between coating and H13 steel substrate, microhardness distribution and wear resistance in the coating were analyzed. The coating from cemented carbide with thickness of 1-3 mm by vacuum powder sintering at temperature ranging from 1280 degrees C to 1300 degrees C was obtained. The experimental results indicated that the coating with microhardness of HV 1600 favorable to wear resistance is strongly bonded with the H13 steel substrate by mutual diffusion and penetration of Fe,Cr,Mo,V in substrate towards the coating and W,Co,Ni in coating towards the substrate.
