电沉积Ni-P复合镀层的研究进展
Electrodeposition of Ni-P composite coatings: A review
摘要：
电沉积Ni-P镀层具有重要的力学、摩擦学和电化学性能。它们还可以表现出催化活性和有益的磁性行为。通过随后的热处理，这种Ni-P涂层的硬度可以接近或超过硬Cr涂层的硬度。在Ni-P基体中均匀分散的第二相粒子的电化学共沉积可以提高沉积物的性能，并满足现代工程涂层的挑战性要求。综述了近年来国内外在电沉积含陶瓷颗粒和固体润滑颗粒的Ni-P复合镀层方面的研究进展。综述了SiC、B_4C、WC、Al_2O_3、SiO_2、TiO_2、CeO_2、MWCNT、MoS_2、WS_2、TiN、六方BN、PTFE及其组合增强NiP复合镀层的研究进展。提出的主要模型的粒子的共沉积，浴流体力学的影响和操作参数的控制举例说明。重要的趋势突出，并总结了未来的R & D的机会。
英文摘要：
Ni-P coatings produced by electrodeposition have important mechanical, tribological and electrochemical properties. They can also exhibit catalytic activity and beneficial magnetic behaviour. With subsequent thermal treatment, the hardness of such Ni-P coatings can approach or exceed that of hard Cr coatings. Electrochemical codeposition of homogeneously dispersed second phase particles within the Ni-P matrix can enhance deposit properties and meet the challenging demands on modern engineering coatings. A general overview of research work on the electrodeposition of Ni-P composite coatings containing included ceramic or solid lubricant particles is provided. Advances in research into NieP composite layers reinforced by SiC, B4C, WC, Al2O3, SiO2, TiO2, CeO2, MWCNT, MoS2, WS2, TiN, hexagonal BN, PTFE and their combinations are considered. Major models proposed for the codeposition of particles, the influence of bath hydrodynamics and control of operational parameters are illustrated by examples. Important trends are highlighted and opportunities for future R & D are summarised.
