预合金粉在金刚石工具中的应用研究

Research and application of pre-alloyed powders for diamond tools

预合金粉的品种繁多,性能可设计、调节范围极其广大,适用于多种金刚石工具,满足各种使用条件,可用于多种生产工艺流程,用户只需通过调节金刚石的品级、浓度、粒度,即可调配出各种用途性能的胎体,节省金刚石制品的研发费用,节约能耗,提高生产效率。实验结果表明:预合金配方粉可提高胎体抗弯强度18%,扩大了烧结温度的范围,提高了锯片切割寿命48%。

The pre-alloyed powders are in wide varieties. Their functions can be designed and their compositions can be adjusted in a extremely large range, to make them to be suitable for a variety of diamond tools, and to meet various conditions of use. They can be used for a variety of production procedures. The users, by simply regulating diamond grade, concentration or particle size, can develop specially purposed matrix for various cutting applications. This can reduce the R＆D cost, save energy and improve production efficiency of diamond products. The experimental results show that the pre-alloyed powders formula can improve the bending strength of matrix by 18% ,expand the scope of the sintering temperature ,and improve the saw blade cutting life by 48%.
