Development of sintering process hard metals to wear resistant efficiency on sustainable material management
This study aims to development of production process of hard metal by tungsten carbide powder with the particle sized of 0.1 - 0.35 µm. This carbide powder were made of recycling cemented carbide tool scraps, so it is mixed ...
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 ...
