摘要

探讨了激光熔化沉积（LMD）技术在制备双金属复合材料（特别是TC4-TA15）中的应用。通过在TC4和TA15钛合金基体上依次沉积互补合金粉末，成功合成了两种不同的双金属样品。研究重点对试样的显微组织、相组成、界面特征和力学性能进行了综合分析。结果表明：与TC4/TA15材料相比，TA15 /TC4复合材料具有更高的屈服强度和极限抗拉强度，其抗拉强度为1055.38 MPa，比TC4基体提高19.18%；在ta15 /TC4界面处形成了一个约30 μm宽的过渡区，具有良好的键合界面，整体性能得到提高。

Preparation of TC4-TA15 Bimetallic Materials by Laser Melting Deposition: Microstructure and Mechanical Properties at the Interfacial Union

The application of laser melting deposition (LMD) technology for the fabrication of bimetallic composites, specifically TC4-TA15, has been explored. Two distinct bimetallic specimens were successfully synthesized through the sequential deposition of complementary alloy powders onto TC4 and TA15 titanium alloy substrates. The research concentrated on the comprehensive analysis of the specimens’ microstructure, phase composition, interfacial characteristics, and mechanical properties. The results showed that the TA 15/TC4 composites had higher yield strength and ultimate tensile strength compared with the TC4/TA15 materials, with a tensile strength of 1055.38 MPa, which was 19.18% higher than that of the TC4 substrate. And a transition region of about 30 μm wide was observed at the TA 15/TC4 interface, which has a good bonding interface and an improved overall performance.
