-based binder was developed for the powder injection molding (PIM) of WC-TiC-Co cemented carbides. The critical powder loading and the rheologic behavior of the feedstock were determined. It was found that the critical powder loading could achieve up to 62.5% (volume fraction) and the feedstock exhibited a pseudo-plastic flow behavior. The injection molding, debinding and sintering processes were......

was prepared by a short-term recycling technique which contains the oxidation and reduction- carbonization procedures. The thermal spray feedstock powder was fabricated by the process consisting of spray... prepared by the recycled composite powder and the commercial feedstock powder were compared. The results show that when the carbon addition is 16.7% (mass fraction), the recycled WC-Co composite has......
