金属结合剂金刚石工具研究进展

Research progress of metal bond diamond tools

金刚石工具广泛用于天然石材、陶瓷、玻璃、混凝土、硬质合金等的磨削和切割,金属结合剂金刚石工具因具有良好的机械和热学性能而成为金刚石工具的主力军。随着新型陶瓷混凝土等加工对象的不断出现和变化,要求金刚石工具要持续改进,以提高其切削效率、减少自身磨损、同时降低其制造和使用成本。本文综述了人造金刚石颗粒的性能、不同类型金属结合剂的成分组成和基本性能、金刚石与金属结合剂的界面结合状态以及提高其结合强度的措施,并对金属结合剂金刚石工具的发展作了进一步展望。

Diamond tools are widely used in the grinding and cutting of natural stone, ceramics, glass, concrete, hard alloys, etc. Metal bond diamond tools have become the main force of diamond tools due to their good mechanical and thermal properties. With the continuous emergence and ever-changing of new ceramic concrete and other processing objects, diamond tools are required to be continuously modified to improve cutting efficiency, slow down wear, and reduce manufacturing and use costs. This paper reviews the properties of synthetic diamond particles, the composition and basic properties of different types of metal binders, the interface state of diamond and metal matrix, and the measures to improve the bonding strength. The further prospects for the development of metal bond diamond tools are put forward.
