GALLING-FREE FINE BLANKING OF TITANIUM PLATES USING CARBON-SUPERSATURATED HIGH-SPEED STEEL PUNCH

A carbon-supersaturated (CS-) high-speed steel punch was prepared using low-temperature plasma carburizing for fine blanking of pure titanium plates.The Beauty bare high-speed steel punch was also prepared as a reference to describe the adhesion and abrasive galling in the fine blanking of the titanium plates, even in a single shot.The CS-punch was

BACKGROUND: Despite the fact that the fixation of nitrogen is one of the most significant nutrient processes in the terrestrial ecosystem, a thorough study of the spatial and temporal patterns in the abundance and distribution of N-fixing Power Cable communities has been missing so far.METHODOLOGY/PRINCIPAL FINDINGS: In order to understand the dyna
