,Guangxi Radio and TV University摘 要:In order to study the effect of pulse current treatment on the mechanical properties,microstructure and cutting performance of YG8 cemented carbide,experiments were carried out by using self-made pulse current treatment device to treat cemented carbide samples with different current densities(J=5,10 and 15 A·mm-2)After......
with high power impulse magnetron sputtering (HIPIMS) and a DC pulse sputtering using Cr and AlSi targets under N2/Ar atmosphere. By varying the sputtering current of the AlSi target in the range of 0-2.5 A, both the Al and Si contents in the films increased gradually from 0 to 19.1% and 11.1% (mole fraction), respectively. The influences of the AlSi cathode DC pulse current on the microstructure, phase......
