Application of cast tungsten carbide particles coated with cobalt powder in diamond saw blades

  • 摘要: 对铸造WC、Co粉包覆铸造WC和Ni粉包覆铸造WC颗粒3种材料在金刚石锯片中的应用进行研究,探究其对金刚石锯片胎体机械性能、微观形貌及锯片切割性能的影响。结果表明:当3种材料与金属粉末的质量比都为3∶1时,形成的3种胎体的硬度相当。含Co粉包覆铸造WC的胎体抗弯强度最高,WC颗粒与胎体界面的结合最紧密,胎体显微组织最致密;含Ni粉包覆铸造WC的胎体的抗弯强度次之;仅加入铸造WC的胎体的抗弯强度最差。与仅加入铸造WC的锯片相比,Co粉包覆铸造WC应用到锯片中,其锯片的切割寿命最长,提高了40%。
