中文摘要：

以商用纯锆为基材，采用激光立体成形技术分别沉积了单层和多层ZkAiCu非晶合金，并对沉积层及其基体界面区域的成分和组织结构进行了分析。结果表明，沉积层主要由非晶构成，晶化程度随着沉积层数的增加无显著增加；沉积层的晶化主要存在于每一层的热影响区，近层间和道间搭接部分晶化最为严重，并且层间的晶化比道间的更显著；沉积层与基体的结合方式为冶金结合，在基体和沉积层间存在一薄层过渡区，其最大厚度仅为35μm，基体的成分稀释主要发生在此过渡区，并在过渡区出现了局部外延枝晶生长。

英文摘要：

Single layer and multilayer Zr55Al0NisCu30 bulk metallic glasses are deposited on the commercial pure zirconium substrates by laser solid forming （LSF）. The composition and microstructure of the deposits are researched. The results show that the deposits are mainly constituted by amorphous materials. The crystallization degree does not increase remarkably with the increase of deposited layers. The crystallization mainly occurs in the overlapping zone between the adjacent traces and layers of the heat affected zone （HAZ）, especially the adjacent layers. The bonding type between deposit and substrate is metallurgy bonding. There is epitaxial growth of dendrites emerging at the thin transition zone which is only 35 tam, the composition dilution mainly occurs in this transition zone,
