(Ti,Zr)C powder was sintered with WC-Co following an industrial process, including an isotherm at 1410 °C. A series of interrupted sintering trials was performed with the aim of studying the sintering behavior and the microstructural evolution during both solid-state and liquid-state sintering. Reference samples, using the same elemental compositions but with the starting components TiC and ZrC...
The development of cemented carbides nowadays is aimed at the application and sintering ultrafine nano-sized powders for production a variety components where excellent mechanical properties high wear resistance are required use in temperature corrosive environment conditions. most efficient way increasing tribological along with achieving corrosion coating. Using surface processes (modificatio...
Tungsten carbonitride [W(C,N)] was deposited on cemented carbide substrates by chemical vapor deposition (CVD) in a hot-wall reactor using tungsten hexafluoride (WF6), acetonitrile (CH3CN), and hydrogen (H2) as precursors. carbides nitrides with hexagonal δ-WC type structure are generally difficult to obtain CVD. Here, it found that the combination of WF6 CH3CN precursors enabled W(C,N) coating...
