预合金粉末的特点有哪些?

  预合金粉末由于每个粉末颗粒都包含组成合金的各种金属元素,因此预合金粉成分均匀性相当好雾化铜粉介绍由于其共熔点比合金中单元素熔点要低得多,在烧结过程中,只要温度达到预合金粉末的液相线以上一点时,整个黏结金属成分的粉末熔化,所以预合金粉末烧结涅度低,使用预合金粉末有以下显著优点:

  (1)预合金粉刀头比机械混合粉末刀头元素分布均匀,从根本上避免了成分偏析;

  (2)预合金粉合金化充分,组织均匀,大大提高了烧结制品的抗压、抗弯强度,易于满足金刚石制品胎体性能要求;

  (3)由于预先合金化大大降低了烧结过程中金属原子的扩散所需的激活能,降低了烧结温度,缩短了烧结时间,可避免金刚石高温损伤;

  (4)绕结温度低。降低了能耗,有利于降低成本;

  (5)减少了石墨模具消耗,也有利于降低成本;

  (6)预合金粉抗氧化能力强,烧结性能好;

  (7)预合金粉胎体具有高硬度和高冲击强度;

  (8)预合金粉可据高对金刚石的把持力,金刚石突出高,从而提高金刚石工具的锋利度,延长工具的使用寿命;

  (9)在切割性能相同的情况下,使用预合金粉可降低金刚石浓度15%~20%,使生产成本更低廉。
