Voltage-current-time characteristic of stabilized zirconia with point contact platinum electrode in argon gas ambient.

Three-electrode current-voltage measurements on erbia stabilized bismuth oxide with co-pressed gold gauze electrodes

The polarization behaviour of (Biz03)0.,5(Er,0,),,25(BE25) with a co-pressed gold gauze electrode was studied as a function of temperature and oxygen partial pressure in a three electrode cell. The anodic polarization is smaller than the cathodic polarization. The cathodic charge transfer coefficient, (Y,, is about 0.5 while the anodic one, (Y., is about 1.5. The exchange current density shows ...

Unusual contact burn due to argon gas.

Series Resonance Based Fault Current Limiter with Controlling The Point of Common Coupling Voltage

This paper proposes a novel Fault Current Limiter (FCL) for the application on distribution networks to control voltage sags at the Point of Common Coupling (PCC) during faults. This new FCL is based on series resonance including resonance transformer and series capacitor. So, by proper design of the series resonance LC tank, the fault current is limited to an acceptable level. The FCL operatio...

ELECTRODE EFFECT ON FLOW CONDITIONS IN ARGON GAS METAL ARE MODELING

A two dimensional mathematical model has been developed for describing the temperature, flow, and electric fields in the are column of the Gas Metal Arc Welding (GMAW) of aluminum in argon shielding gas using axisymmetric Navier-Stokes, Maxwell, and differential thermal energy equations. The predicted results are most sensitive to the cathode spot radius and an optimum cathode spot radius exist...

TTRIA STABILIZED ZIRCONIA DOPED WITH Bi 203

Yttria stabilized zlrconia doped with Bi203 shows an efficient luminescence due to the Bi 3+ ions. Two luminescent centres were observed which are ascribed to BIO 8 and BiO 7 groups.
