- 摘要:
- 采用超声破碎法制备了含纳米Cr3C2颗粒的钴镍镀液，研究了未加分散剂，以非离子型高分子分散剂改性和以阴离子分散剂改性三种情况下的镀液性能。通过激光粒度仪、镀层中颗粒复合量等测试方法对纳米Cr3C2颗粒钴镍镀液的稳定性进行了表征。结果表明，含纳米Cr3C2颗粒钴镍镀液通过阿拉伯树胶高分子型分散剂改性后，镀液的稳定性最佳，当阿拉伯树胶添加量为0.3 g/L，超声时间为0.5 h时，所得纳米Cr3C2颗粒钴镍镀液的稳定性最好。
- Abstract:
- Cobalt-nickel plating bath containing Cr3C2 nano-particles was prepared by ultrasonication. The properties of the plating bath without dispersant, modified by non-ionic macromolecule dispersant and modified by anionic dispersant were studied. The stability of Co-Ni plating solution containing Cr3C2 nano-particles was characterized by the method of laser particle size analysis and particle composite amount. The results indicate that the Co-Ni plating solution containing Cr3C2 nano-particles modified by gum arabic polymer dispersant has optimal dispersion stability. When the amount of gum arabic is 0.3 g/L and the ultrasonic time is 0.5 h, the Co-Ni plating solution containing Cr3C2 nano-particles has the best stability.
