摘要: 针对鼓风机用FV520(B)钢叶片根部气蚀裂纹的激光再制造,采用正交化试验方法优化再制造工艺参数;通过分析FV520(B)钢叶片模拟件根部破损情况,制定激光扫描修复方案,观察和分析修复部位金相显微组织及物相组成,并对熔覆层硬度进行测试。试验结果表明:激光功率1.1 kW、扫描速度250 mm/min、送粉速率8.10 g/min及载气流量150 L/h为该再制造系统下该材料优化工艺参数;采用多种扫描路径相综合的修复方式,减少层间热累积效应,使修复件尺寸精度保持在0.8 mm之内;熔覆层和基体为良好的冶金结合,熔覆层表面显微硬度最高,平均值达到675 HV0.2,结合界面处硬度值达到610 HV0.2,具有较好的组织结构和硬度性能。

Abstract: Aiming at the laser remanufacturing of gas corrosion crack in the root of the FV520(B) steel blade for air blower, remanufacturing process parameters were optimized through orthogonal experimental analysis. Through analyzing the breakage in the root of FV520(B) steel blade simulator, the repairing scheme for laser scanning was planned, the metallographic structure and phase composition of the repaired region were observed and analyzed, the hardness was also tested. The results show that, the 1.1 kW laser power, the 250 mm/min scanning speed, the 8.10 g/min power feeding rate, the 150 L/h carrier gas flow are the optimized process parameters for special material and remanufacture system,the multi-scanning paths are synthetized to decrease the thermal cumulative effect between layers, the dimension precision between the repaired and the original one is 0.8 mm, there is strong metallurgical bonding between the cladding layer and the substrate, the hardness of the cladding layer surface is the highest, its average value is 675 HV0.2, the interface can reach 610 HV0.2, the cladding layer has better metallographic structure and hardness property.
