| 中文摘要: |
| 为研究激光表面合金化工艺对镀铬后30CrMnSi组织与硬度的影响，以C02激光器为热源，采用正交试验法，对其表面进行单道扫描，获得了金相组织和显微硬度均优于基体的合金化层。研究结果表明：激光合金化层晶粒显著细化，平均硬度明显高于基体硬度。激光功率500W，扫描速度10 mm/s，保护气体流量10L/min时，合金化层组织细小均匀致密，最高硬度达829HV，约是基体硬度的2.6倍。 |
| 英文摘要: |
| For studying the impact of microstructure and micro-hardness of 30CrMnSi electroplated with Cr by laser surface alloying, using C02 laser as heat source and orthogonal test, the alloying layers by single-channel scanning were attained whose microstructure and micro-hardness were better than the substrates: The results indicate that: the laser alloying layers microstructure is refined remarkably, and the average micro-hardness is higher than the substrates'obviously. When laser power is 500W, scanning speed is lOmm/s and the protection of gas flow is lOL/min, the alloying layer has small dense uniform and the highest micro-hardness of 829HV is about 2. 6 times in contrast of the substrate's. |
