目前,碳化钨复合复粉末材料一般均采用机械方式制造生产,其晶粒度大小均高出500nm以上.美国Nanodyne Inc公司(地址NewBrunswick N·J)是世界上目前唯一能够试制出纳米级超细碳化钨复合粉末材料的厂家,其粉末晶粒度大小均低于机械制造的碳化钨复合粉末的十分之一.范围在1～100nm的碳化钨复合粉末均能试制,而且具有很多新的特点.在当今世界上,对纳米级超细复合粉末的认识才刚刚起步,世界上只有几家著名的公司(生产硬质合金刀片和切削刀具的厂家)正在对20～50nm的超细碳化钨复合粉末材料进行评估和试验,目的是想从各方面来了解并证实其新型超细复合粉末材料的各种性能.据开发这种超细碳化钨复合粉末材料的Nanodyne Inc公司声称,这种纳米级超细碳化
At present, the tungsten carbide composite powder materials are generally used mechanical manufacturing, the grain size are higher than 500nm above the United States Nanodyne Inc (Address NewBrunswick N · J) is currently the world can only try to produce nanoscale ultrafine Tungsten carbide powder composite material manufacturers, the grain size of the powder are less than mechanical manufacturing of tungsten carbide powder one tenth of the range of 1 ~ 100nm tungsten carbide powder can be trial production, and has many new features In today ’s world, the understanding of nano - sized ultrafine composite powder has just started, and only a few famous companies in the world (manufacturers of carbide cutting inserts and cutting tools) are compounding 20 ~ 50nm ultrafine tungsten carbide Powder materials were evaluated and tested in an attempt to understand and demonstrate the various properties of their new ultrafine composite powder materials in all aspects.According to Nanodyne Inc. which developed this ultrafine tungsten carbide composite powder material, Superfine carbonization
