Abstract

AlSi10Mg is widely used in additively manufacturing aeronautical lattice and honeycomb structures. The unclear complex quality characteristics has been an obstacle of nondestructive testing of additive manufacturing (AM) AlSi10Mg, especially at its as-built state. This article attempts to reveal the quality characteristics of as-built AM aeronautical AlSi10Mg based on its conductivity characteristics. Experimental results show that the quality of manufacturing is nonuniform. The nonuniformity of each sample surface is systematically evaluated. Along the building direction, the quality is best in the initial few layers and decreases as the built height increases. On this basis, a reference curve is obtained and used to describe the quality characteristics of as-built AM component along the building direction. Based on the quality characteristics, the inspection of small offsets caused by accidental failures during the manufacturing process is carried out. The offsets not <37 μm are detected with the help of the reference curve, whereas they are not discovered by the radiography testing. It proves that the proposed method of offset inspection is highly sensitive.

航空AlSi10Mg增材制造质量特性无损评价及偏移量检测

AlSi10Mg 广泛应用于航空晶格和蜂窝结构的增材制造。复杂的质量特性不明确一直是对增材制造（AM）AlSi10Mg 进行无损检测的障碍，尤其是在坯料状态下。本文试图根据航空 AlSi10Mg 的电导率特性来揭示其竣工后的质量特性。实验结果表明，制造质量是不均匀的。对每个样品表面的不均匀性进行了系统评估。沿着建筑方向，最初几层的质量最好，随着建筑高度的增加，质量下降。在此基础上，我们得到了一条参考曲线，用于描述沿建筑方向竣工的 AM 组件的质量特性。根据质量特性，对制造过程中意外故障造成的小偏差进行检查。非
