摘要
由于纯铂硬度较低,改善其硬度和强度对铂饰品应用具有重要意义。重点从合金化和加工工艺两个方面综述了目前铂饰品的主要强化方式,包括固溶强化、时效强化和细晶等合金化强化方式及其强化机制以及热等静压和表面硬化技术等现代加工工艺。提出了未来应用热等静压工艺以及新型强化材料的选用改善铂饰品材料的加工性能的必要性和迫切性。
Due to the low hardness of pure platinum,it is of great significance to improve its hardness and strength for platinum jewelry applications.This paper summarizes the main strengthening methods of platinum jewelry from alloying and processing technology aspects.The alloying approach covers solid-solution strengthening,aging hardening,alloying hardening and their strengthening mechanisms,while the processing technologies consist of thermal isostatic pressing and surface hardening.It is necessary and urgent to improve the processing performance of platinum jewelry materials by using hot isostatic pressing technology and the selection of new reinforced materials in the future.
