Attention Cemented Carbide Producers: How Precision Carbon Control in Vacuum Sintering Furnaces Prevents Carburization/Decarburization

In cemented carbide production, carbon content is the lifeline. Too high → Free carbon (carburization), increased brittleness. Too low → η phase (decarburization), reduced strength. A ±0.1% carbon fluctuation can turn a first-grade batch into scrap. For WC-Co cemented carbides, carbon content typically must stay within ±0.05-0.1%. Beyond this range, microstructure fails. The key to achieving this precision? Your vacuum sintering furnace's carbon potential control capability.
