摘要
随着黑钨资源的枯竭,储量丰富、杂质含量高的白钨替代黑钨制备硬质合金成为未来的发展趋势,杂质元素对钨产品结构及性能的影响是急需解决的科学问题。综述了在硬质合金制备过程中杂质元素的种类及演变情况,着重介绍了杂质元素对不同阶段钨产物形貌、晶粒度、结构及性能的影响,以期为以白钨资源制备硬质合金的研发与生产提供理论基础。
With the consumption of wolframite resources, it is an inevitable trend that abundant, high impurity content of schedite alternate wolframite to prepare cemented carbide in the future. The problem about influence of im- purity elements on structure and performance of tungsten products is in need of immediate solution. The type of impu- rity elements in cemented carbide preparation and evolution are reviewed, and the impact of impurity elements on mor- phology, grain size, structure, and properties in different stages is highlighted, hoping to provide a theoretical basis for using scheelite as raw material to develop and produce tungsten carbide.
