钛合金-镍基高温合金异种材料复合结构能充分发挥两种材料各自的优势,实现性能互补,在航空发动机制造领域具有重要应用前景。本工作针对TC4-GH4169异种材料复合结构,设计了(V-15Cr)+ 0Cr13中间过渡层结构,并采用激光熔融沉积技术进行制备,研究激光功率和粉末铺叠方式对激光熔融沉积TC4-GH4169异种材料界面冶金质量的影响。结果表明,(V-15Cr)+ 0Cr13复合中间层界面冶金控制是影响TC4-GH4169异种材料冶金质量的关键因素。采用送粉式激光熔融沉积工艺,当激光功率为400 W时,由于激光能量较低,0Cr13和V-15Cr之间未发生有效冶金反应,出现了层间剥离现象;采用600 W激光功率,(V-15Cr)/0Cr13界面出现了少量的脆性σ相;当功率增加至800 W时,0Cr13和V-15Cr熔覆层之间具有较大的稀释率,界面处形成了层厚约为20 μm且连续分布的σ相。采用预置粉末的激光熔融沉积工艺,并使激光焦点处于V-15Cr熔覆层的表面,可使0Cr13和V-15Cr熔覆层之间的稀释率控制在合理水平,有效避免了界面σ相的形成。剪切实验结果表明,断裂发生在V-15Cr合金层,界面强度达到299 MPa,强度系数达到0.61。 |

The titanium alloy-superalloy dissimilar material composite structure can give full play to the respective advantages of the two materials and achieve complementary performance, which has important application prospects in the field of aeroengine manufacturing. In this paper, the (V-15Cr)+0Cr13 intermediate layer structure was designed for TC4-GH4169 composite structure, and was prepared by laser melting deposition technology. The effects of the laser power and the powder stacking method on the metallurgical quality of the interface of the laser melting deposited TC4-GH4169 dissimilar material were studied. The results show that the interface metallurgical control of the (V-15Cr)+0Cr13 composite interlayer is a key factor affecting the metallurgical quality of TC4-GH4169. For the powder feeding laser melting deposition process, when the laser power is 400 W, there is no effective metallurgical reaction between 0Cr13 and V-15Cr due to the low laser energy, resulting in interlayer peeling; when the laser power is 600 W, a small amount of brittle σ phase appears at the interface of (V-15Cr)/0Cr13; when the laser power is increased to 800 W, there is a greater dilution ratio between the 0Cr13 and V-15Cr cladding layers, and the continuously distributed σ phase with a thickness of about 20 μm is formed at the interface. By using powder presetting laser melting deposition process and focusing the laser on the surface of the V-15Cr layer, the dilution ratio between the 0Cr13 and V-15Cr cladding layers can be controlled at a reasonable level, the formation of the σ phase at the interface can be effectively avoided. The shear test results show that the fracture occurs in the V-15Cr alloy layer. The interfacial strength reaches 299 MPa and the strength coefficient reaches 0.61. |
