摘　　要：介绍了RE元素对W18Cr4V高速钢离子SNC共渗组织和耐磨性的影响。结果表明 ,RE对改善组织 ,提高表面硬度 ,使渗层硬度梯度平缓 ,均可起到明显的作用。可有效地提高抗摩擦磨损 。In this paper the influence of RE elements on the microstructure and wear resistance of Ion-Sulpho-nitrocarburizing 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.
