添加剂加量对金刚石焊接强度的影响(金刚石焊接机理研究之三)

Effect of the Additive Amount on Diamond Welding Strength (Part

摘要:

通过加入不同含量添加剂的2种试样,用同一烧结工艺同炉烧结,对试样进行强度测试,获得了不同的物理力学性能.在高倍电镜下,观察和测量金刚石与胎体金属界面上不同添加剂所生成的金属碳化物层厚度和面积.通过试样金相组织分析,观察其晶体组织及颗粒分布,从而确定不同添加剂的合理加量值.

Abstract:

Two testing samples each with different additive amount were sintered in the same furnace with the same sintering process and then tested for their strength. The resulting physical and mechanical properties of them are different. The thickness and area of the metallic carbide generated from different additives on the interface between the diamond and the metallic matrix were observed and measured under high power electronic microscopes. The proper amount of different additives is determined through analysis of the metallurgical system of the samples and observation of its crystal organization and particle distribution.
