树脂结合剂超硬制品中铜锡合金粉的应用与分析

Application and analysis of copper-tin alloy powder in resin bond superhard products

本文采用铜锡合金粉作为树脂结合剂的添加剂,分析了铜锡合金粉的铜锡比例、含量、粒度对树脂结合剂超硬制品力学性能的影响;利用扫描电镜(SEM)分析了树脂结合剂超硬制品的微观结构;通过磨削试验研究了铜锡合金粉填充的树脂结合剂金刚石砂轮的磨削性能。结果表明:铜锡合金粉的铜锡比例、含量、粒度对树脂结合剂超硬制品的力学性能有较显著的影响;铜锡合金粉填充的树脂结合剂金刚石砂轮的磨削性能优于铜粉填充的树脂结合剂金刚石砂轮的磨削性能,磨削比显著提高。

This research took copper-tin alloy powder as an additive in the resin bond.The influences of the proportion of copper and tin,content and particle size of copper-tin alloy on the resin bond superhard products were studied.The microstructure of the resin bond superhard products was analysed by scanning electron microscope（SEM）.The grinding performance of the resin bond diamond grinding wheel filled with copper-tin alloy was studied by the grinding experiment.The results showed that,the proportion of copper and tin,content and particle size of copper-tin alloy had significant influences on the mechanical properties of the resin bond superhard products.The grinding performance of the resin bond diamond grinding wheel filled with copper-tin alloy powder was better than that of the resin bond diamond grinding wheel filled with copper powder.
