| Abstract: | The influence of RE elements on the microstructure and wear resistance of ion-sulph-carbonitriding for cast high speed steel modified by Y-K-Na was studied.The results showed that RE elements have an action on reforming structure enhancing surface hardness and having a smoothly depth hardness gradient of cross-section of its layer.The adhesive wear and abrasive wear resistance of its layer can be improved. |
