摘要:
通过实验研究,提出空气状态下采用等离子熔射金属焊接金刚石的新方法.将等离子体熔化的钛金属熔滴,喷射至经王水浸蚀的,采用热压烧结方法制备的金刚石节块表面,然后制备自然断口以观其微观状态.通过SEM照片,研究断口中金刚石经过热压烧结与熔射沉积后的金属与金刚石界面微观状态; 分析比较被熔射金属包镶的金刚石与被热压烧结的金属粉末包镶的金刚石,以及与其包镶体之间的结合强度的差异.最后,对金属与金刚石之间的界面形成机制进行初步的探讨.
Abstract:
A new method for diamond brazing by plasma-spray-forming under air condition has been carried out.In experimental study,Ti powder was chosen for spraying onto eroded diamond segments made by hot-pressing sintering,fracture on which was made for microscope investigation.The scanning electronic microscopy(SEM) photos of fracture of diamond segment had been made to investigate on the interfaces between diamonds and metals formed by plasma-spraying and hot-pressing sintering respectively.And also,the difference of combination intensity of diamond and its binding body made by hot-pressing sintering or by plasma-spray forming was analyzed and compared in the same way.A fundamental discussion on the forming mechanism for the interface between diamond and metal formed by plasma-spraying was put up.
