Development of wear resistance microstructure of hardmetals by sintering process
This study developed the cemented tungsten carbide by steadily sintering at 1430 °C for one hour. The tungsten carbide structure is a long shape. Its grain size has a difference between width and length, and there are high ...
Development of nano-tools product by tungsten carbide powder nanosized in Thailand
The tungsten carbide powder which recycled from the scarps of cemented tungsten carbide, produces the purity of 99%. Using this tungsten carbide powder to manufacture a cutting tool and test its properties are the main ...
Development of tungsten carbide recovery for the hard metal
This research was on the production of hardmetal from recovery of tungsten carbide tool scraps, recycling through ball milling for 40 hours. The metal powder obtained, which was of the size between 0.11-0.22 µm, was ...
Development of Nano-sized WC powder from recovery of cemented tungsten carbide scraps
WC powder was obtained from recycling cemented carbide scraps. This metal power contained tungsten carbide (WC) at 89.17%, titanium (Ti) at 4.90%, tantalum (Ta) at 3.56%, niobium (Nb) at 1.31% and molybdenum (Mo) at 0.93%. ...
