This paper aims to study the effects of different brazing temperatures and holding time on the exposing height of the brazing diamond and wetting angle of the solder, and to analyze the morphology and composition of the reaction products at the interface between the diamond and the solder. Using the Ni-Cr-B-Si composite solder, the orderly arrangement method, the flame spraying process, and the remelting technology–based vacuum carbon tube furnace, the sample block with single layer ordered diamond is prepared. The results show that with the increasing of brazing temperature, the exposing height of the diamond, and the wetting angle of the solder decrease, and with the increasing of holding time, the exposing height of the diamond increases, and the wetting angle of the solder decreases. In addition, the fine acicular Cr-C compounds are formed at the brazing interface between diamond and solder, which prevents the increasing of wetting capacity of solder. The study of the effects of brazing temperature and holding time on the brazing quality, and the analysis of the morphology and composition of the products in the brazing interface, provide important technical and theoretical support for the better production of brazing diamond tools.

钎焊温度和保温时间对钎焊金刚石润湿性的影响及钎焊界面分析

本文旨在研究不同钎焊温度和保温时间对钎焊金刚石暴露高度和焊料润湿角的影响，并分析金刚石与焊料之间界面处反应产物的形态和组成。使用Ni-Cr-B-Si复合焊料，有序排列方法，火焰喷涂工艺以及基于重熔技术的真空碳管炉，制备了单层有序金刚石样品块。结果表明，随着钎焊温度的升高，金刚石的暴露高度减小，钎料的润湿角减小；随着保持时间的增加，金刚石的暴露高度增大，钎料的润湿角增大。减少。此外，在金刚石和焊料之间的钎焊界面上会形成细小的针状Cr-C化合物，从而阻止了焊料润湿能力的提高。研究钎焊温度和保温时间对钎焊质量的影响，并分析钎焊界面中产品的形貌和成分，为更好地生产钎焊金刚石工具提供了重要的技术和理论支持。
