| 摘 要： | 研究了45 钢硼-稀土-铬共渗组织和性能。结果表明:与单渗硼层相比, 由于共渗层中稀土和铬的存在, 硼-稀土-铬共渗层的显微组织、显微硬度、脆性和耐磨性得到改善, 尤其耐磨性得到显著提高。

| Abstract: | The microstructure and properties of the B-RE-Cr coinfiltration layer for Steel 45 are investigated. The results show that comparing with mono-boronizing layer, the co-boronizing layer's microstructure, microhardness, brittleness and wear-resistance are greatly improved. |
