摘要: 提出采用低温化学镀工艺方法制备陶瓷/金属功能梯度材料的设想, 利用自制的化学镀装置对制备SiC/Ni-P FGM 进行了实验研究。结果表明, 通过优化化学镀工艺, 调整施镀时间和SiC 微粒的添加速度及添加量等参数, 可以合适地控制材料镀层的厚度和成分梯度分布。功能梯度材料的微观结构和力学性能等都与材料成分梯度分布之间有很好的对应关系。Abstract: A new method of producing ceramic/metal functionally gradient material by electroless plating technique was proposed. The preparation of SiC/Ni P FGM was carried out by self made electroless plating facilities. The results show that the thickness of FGM coating and the gradient distribution of composition can be controlled by changing the parameters such as plating time, the addition speed and concentration of SiC particles after optimizing electroless plating technology. The good corresponding relationships among the SiC content, the microstructure and the mechanical property of the FGM are obtained.
