Characterization of Recycled Cemented Carbide and the Raw Materials

Abstract:

Nowadays, a large quantity of cemented carbide is being consumed, and the amount of scrap cemented carbide is increasing year by year. In this paper, crystal morphology, element content and phase structure of the recycled cobalt powder as well as recycled tungsten carbide powder were characterized by SEM, EDS and XRD. Hardness of the prepared W-Co alloy using recycled cobalt powder and recycled tungsten carbide powder as the raw materials was tested by Rockwell apparatus. Through analysis of these results, the existing problems in recycling of scrap cemented carbide emerged. As for recycling of scrap cemented carbide, the research results can provide theoretical basis for improvement of recycling technology and process control technology.
