Comparison of Property of Dynamic Melting-Loss H13 Steel by Different Surface Treatment
In order to prolong the service life of Aluminum alloy die casting dies, different surface treatments were adopted to avoid melting loss on the surface of the dies. In this paper, the dynamic melting-loss properties of H13 steel were compared among non-treatment, vapor oxidation treating, carbonitriding and composite treatment of nitirding and vapor oxidation in liquid aluminum of ADC12 at 700 °C by the weight loss method. The surface structures of the specimens after treatments were analyzed by the optical microscopy (OP); the patterns of specimens on the surface were observed by measuring microscope and the melting-loss characteristics of specimens with different treatment were analyzed. The results showed that the melting-loss property was heightened obviously by different surface treatments; especially the melting-loss property of the specimens with composite treatment of nitirding and vapor oxidation was the best.
