| 中文摘要: |
| 采用激光熔覆技术,在 45#钢表面制备 WO3-V2O5-C 镍基熔覆层。 分析了熔覆层的显微组织,测试了熔覆层的显微硬度,研究了熔覆粉末中 WO3-V2O5-C 的含量及激光功率对熔覆层硬度的影响。 结果表明:采用 WO3+V2O5+C 质量分数为 25% 的熔覆粉末,以 1 . 4 kW 功率进行激光熔覆,所得熔覆层硬度最高,平均值高达1400 HV0 . 3 ,可大大提高材料的耐磨性。 |
| 英文摘要: |
| The WO3-V2O5-C Ni-based cladding layer has been prepared successfully by laser cladding on steel 45#substrate. The microstructure of cladding layer was analyzed, the microhardness of cladding layer was measured, the effect of WO3-V2O5-C content and laser power on the hardness of cladding layer was researched. The result shows that the microhardness of mass fraction of 25 % WO3+V2O5+C cladding layer is maximum in 1 . 4 kW power,and the average value of microhardness is up to 1400 HV0 . 3 . The wear resistance of the cladding layer is greatly improved. |
