Achievements and Developing Prospects of Composites Based on Precious Metals:(II) Systems of Precious Metals Composites

贵金属及其合金作为组元材料,可与其他金属、陶瓷、碳、化学化合物、金属间化合物以及聚合物结合,构成贵金属复合材料。在贵金属复合材料中,贵金属及其合金可作为基体材料,为纤维状或颗粒状的其他材料强化;亦可以涂层、纤维和颗粒等形式作为功能相材料分布在其他基体材料中。本文是“贵金属复合材料的成就与展望”系列文章的第二部分,总结了贵金属复合材料的种类,包括层状复合、纤维复合和颗粒复合材料;列举了贵金属复合材料的主要体系及其应用;讨论了一些贵金属复合材料的结构特征及其今后研究的新课题。

The precious metals and their alloys, as component materials, could be combined with other metals, ceramics, carbon, chemical compounds, intermetallic and polymers forming precious metals composites. In the precious metals composites, the precious metals and their alloys could be used as the base materials reinforced by other materials in the forms of fibers or particles, or as the function phase materials in the forms of coatings, fibers, or particles distributed in the base materials. This paper is the second part of the series papers of ＂Achievements and Developing Prospects of Composites Based on Precious Metals＂. In the present paper, the categories of precious metals composites including the layered-, fiber-and particle composites were summarized, the main systems and their applications of precious metals composites were listed, the structural features of some composites were discussed, and several new questions for study were raised.
