peak discharge
1.This voltammogram indicated that only one electrochemical reaction, corresponding to the peak pair shown around 3.4V vs. Li/Li+, occurred during the charge and discharge of the LiFePC>4. The chemical diffusion coefficient of lithium(DLi+) was measured by using the potential step Chronoamperometry method(PSCA).
4.This paper presented the test of electrical discharge grinding(EDG) of polycrystalline diamond(PCD) with normal electrical discharge machine tool and rotating device. The effects of wheel speed,open-circuit voltage,peak current,pulse duration,and pulse interval of EDG on the material removal rate(MRR),the wheel wear and surface roughness(SR) were investigated respectively.
5.Using the pulse power,taking the hard metal Zr as electrode,45 steel as substrate in the solution containing C through pulse discharge,ZrC ceramic coating was prepared. The microcosmic hardness and thickness of the coating were measured,the influnce of the process parameters of peak current and pulse width on the thickness of the coating was dissused.
