摘要:
为了研究激光熔覆工艺参数对熔覆层宏观形貌和气孔缺陷的影响,通过设计正交试验,分析了优化参数下熔覆层的微观组织和力学性能。试验结果显示,随着扫描速度增加,气孔数量和熔覆层厚度减小;当熔覆层厚度小于200 μm时,Ar气卷入熔融金属形成的气泡能够及时逸出,使得气孔数量降低;在激光功率1 300 W、送粉速度28 g/min、扫描速度7 mm/s的熔覆工艺参数下,能够获得无裂纹和无气孔的熔覆层,其微观组织由大量的针状马氏体和少量的碳化物组成,显微硬度值约为650HV0.5~710HV0.5。研究表明,扫描速度对气孔数量和熔覆层有着显著影响。
Abstract:
In order to study the effect of laser cladding process parameters on the macroscopic morphology and pore defects of the cladding layer, the microstructure and mechanical properties of the cladding layer under optimized parameters were analyzed by orthogonal design test. The experimental results show that the number of pores and the thickness of cladding layer decrease with the increase of scanning speed. When the thickness of the cladding layer is less than 200 μm, the bubbles formed by the Ar gas involved in the molten metal can escape in time, resulting in the reduction of the number of pores. Under the cladding process parameters of laser power 1 300 W, powder feeding speed 28 g/min and scanning speed 7 mm/s, the cladding layer without cracks and pores can be obtained. The microstructure of the cladding layer is composed of a large number of acicular martensite and a small amount of carbide, and the microhardness is about 650HV0.5~710HV0.5. The results show that the scanning speed has a significant effect on the number of pores and the cladding layer.
