提高金刚石砂轮工作性能的发展方向之一是使用镀有一层金属的金刚石粉。苏联波尔塔瓦人造金刚石和金刚石工具厂已生产出金属结合剂MB1的砂轮。乌克兰科学院超硬材料所与该厂共同研制出一种对金刚石粉镀金属层的新配料,这种配料同以前用的配料相比较具有高的毛细管特性并且对金刚石有更高的粘合力。新镀层(以A3标记)具有较高的硬度(达HR C33)和较高的强度(达400Mpa)。新镀层的金刚石砂轮在实验室和生产条件
One of the development directions to improve the working performance of diamond grinding wheel is to use diamond powder coated with a layer of metal. The Soviet Union Poltava synthetic diamond and diamond tool factory has produced a metal binder MB1 grinding wheel. The Institute of Superhard Materials of the Ukrainian Academy of Sciences has teamed up with the plant to develop a new formulation for diamond powder metallurgy that has high capillary properties compared to previous formulations and a higher adhesion to diamond. The new coating (marked A3) has higher hardness (up to HR C33) and higher strength (up to 400 Mpa). Newly coated diamond wheel in laboratory and production conditions
