| 目 的 提高 304 不锈钢表面耐磨性能。 方法 利 用 双辉等离 子合金化技术, 使 304 不锈钢表面形成 Mo 合金化渗层。 分析渗层的成分分布和相结构, 对比基体材料和 Mo 合金化改性层的硬度、磨痕形貌和摩擦磨损性能。 结果 所制 备的 Mo 合金化渗层均 匀 致密, 厚 9. 6 滋m, 主要由纯 Mo 相构成。 合金化元素 Mo 在渗层中从基体表面到 内 部呈梯度分布, 表面显微硬度值达 806HV0. 05。 在干摩擦条件下,Mo 合金化渗层的比磨损率仅为 304 不锈钢基体的 1 /84, 使材料的抗磨损性能得到 明 显改善。 结论 双辉等离 子 Mo 合金化能够有效改善 304 不锈钢的抗磨损性能。 |

| Objective To improve the wear resistance performance of 304 stainless steel. Methods A Mo alloying layer was formed on the surface of 304 stainless steel using the double-glow plasma alloying technique. The composition distribution and phase structure of the modified layer were analyzed. The hardness, the cross-section morphology of wear scar and friction, and the wear properties of substrate and Mo alloying layer were compared, respectively. Results The Mo alloying layer prepared was homogeneous and compact, and the thickness of the alloying layer was about 9. 6 滋m. The layer mainly consisted of Mo, and the Mo element in the alloying layer showed a gradient distribution from the surface to the underlying substrate. The average surface microhardness value was about 806HV0. 05. Under dry friction conditions, the wear rate of 304 stainless substrate was about 84 times higher relative to that of the Mo alloying layer, leading to significantly improved wear resistance. Conclusion Double-glow plasma molybdenizing technique could effectively improve the anti-wear properties of the 304 stainless steel. |
