Tungsten/Molybdenum Carbide TRIZ Cases
- Tungsten Carbide Powder Direct Carburizing Process
Direct carburizing produces tungsten carbide powder with controlled crystallite size, resolving industrial scalability challenges.
- Tungsten Carbide Purification via Cationic Metal Oxidant
Cationic metal oxidants solubilize impurities in tungsten carbide, reducing energy consumption and processing steps compared to traditional recycling.
- Tungsten Carbide Powder Chromium Grain Boundary Control
Chromium-concentrated regions at grain boundaries reduce powder volume and inhibit abnormal grain growth during sintering.
- Tungsten Carbide Powder Chromium Homogeneity
Dissolve chromium compounds in alcohol to mix with tungsten oxide powder, preventing segregation during sintering.
- Ultra-Low Thermal Conductivity Cemented Carbide Alloy
A cemented carbide alloy combines tungsten and titanium carbides with a nickel-molybdenum binder to achieve ultra-low thermal conductivity.
- Spherical Tungsten Carbide via Carbon Coating and Plasma
Carbon coating prevents decarburization during plasma spheroidization, maintaining stoichiometry and wear resistance.
- Cemented Tungsten Carbide with Rhenium for HPHT Deformation Resistance
Adding rhenium to the cobalt binder phase prevents eta-phase formation and maintains structural integrity under high pressure.
