Development of Creep-Resistant Tungsten Carbide Copper Cemented Carbide
Fine-grained tungsten carbide copper (WC-Cu) cemented carbide was sintered via spark plasma sintering at 1773K using a fine WC powder with a mean particle size of 0.11 mm. The mechanical properties were compared with tungsten carbide cobalt (WC-Co) cemented carbide and a binderless WC-sintered material. The Vickers hardness and fracture toughness obtained by the indentation fracture method for ...
متن کاملHydrothermal Degradation of Glycerol by Electrolysis in Subcritical Water
Biodiesel has become an attractive fuel recently, because it is renewable, non-toxic, biodegradable, environmentally friendly, etc. With the increase in the production of biodiesel, the problem of disposing crude glycerol, which is produced as main by-product from biodiesel process such as transesterification, has been raised. Therefore, we have been developing a new green technology-Hydrotherm...
متن کاملChromium and phosphorous recovery from polluted water by hydrothermal mineralization
Detoxification of polluted water containing chromium and phosphorous and its resource recovery were investigated by hydrothermal mineralization using Ca(OH)2 or CaCl2 mineralizers. Under the optimum treatment condition for removing chromic acid (at 473 K, for 2 h using CaCl2 mineralizer in an in situ sampling-type autoclave), CrO4 was recovered as CaCrO4 and the concentration in the treated-wat...
متن کاملProduction of Silicon Carbide Liquid Fertilizer by Hydrothermal Carbonization Processes from Silicon Containing Agricultural Waste Biomass
Wastes from agriculture or sewage systems have several properties, such as huge volume, high humidity, and high organic composition. According to past studies, sugarcane extract, peanut shells and rice husks have high silicon content. Chemical conversion of biomass feedstock will enhance usage and provide value to agricultural waste. In this research, we applied hydrothermal carbonization to co...
متن کاملDevelopment of Cemented Carbide Tool of Reduced Rare Metal Usage
Cemented carbides, including coated cemented carbides, account for 75% of the cutting tools market because of their features such as high hardness, toughness, and the responsiveness to iron, through the use of tungsten carbide for their main hard phases and cobalt for their bonding metals. The consumption of tungsten continues to increase as the amount of carbide tool production increases with ...
