- 摘要:
- 利用3D打印技术制造的高温合金异形内孔道表面较粗糙，针对该问题研发了一种化学抛光液，并考察了化学抛光对其表面形貌、结构及耐腐蚀性能的影响。结果表明，抛光液含硫酸 50 g/L、磷酸30 g/L、十二烷基硫酸钠1 g/L、NNO 5 g/L、缓蚀剂A 4 g/L，温度为50 ℃、抛光时间为20 min时的抛光效果最好，且能显著降低异形通道表面粗糙度。抛光前后镍、铁的特征峰未发生明显变化，说明化学抛光并未对合金表面元素分布及晶体结构产生不良影响。阳极极化曲线和交流阻抗测试显示化学抛光后合金内流道表面耐腐蚀性能明显提高。
- Abstract:
- The surface of the 3D printing alloy inner channel was rough commonly, a special chemical polishing solution was prepared to solve the problem, and the effect of the polishing on the surface morphology, structure and corrosion resistance were investigated. The results showed that under the conditions of sulfuric acid concentration of 50 g/L, phosphoric acid 30 g/L, sodium dodecyl sulfate 1 g/L, NNO 5 g/L, corrosion inhibitor 4 g/L, temperature of 50 ℃ and time of 20 min, the polishing could reduce the surface roughness significantly. There was no change of the diffraction peak of Ni and Fe indicated that the chemical polishing had no bad effect on the surface element distribution and the crystal structure. In addition, the results of anodic polarization curve and electrochemical impedance spectroscopy (EIS) tests showed that the polishing improved the corrosion resistance of the alloy efficiently.
