标准范围

ISO 3908:2009规定了测定碳化物和硬质合金中不溶性(游离)碳质量分数的重量法。本方法适用于铪、钼、铌、钽、钛、钒、钨和锆的碳化物,这些碳化物和粘结剂金属的混合物,不含润滑剂,和由这些碳化物生产的所有等级的预烧结或烧结硬质合金,具有0.02%至0.5%的不溶性碳的质量分数。

ISO 3908:2009 specifies a gravimetric method for the determination of the mass fraction of insoluble (free) carbon in carbides and hardmetals.This method is applicable to

  • carbides of hafnium, molybdenum, niobium, tantalum, titanium, vanadium, tungsten and zirconium,
  • mixtures of these carbides and binder metals, free of lubricant, and
  • all grades of presintered or sintered hardmetals, produced from these carbides,
having a mass fraction of insoluble carbon between 0,02 % and 0,5 %.
